I got this idea for a oneshot after a) the Romeo and Juliet section in my English class combined with b) the Goo Goo Dolls song Let Love In (Listen to it, it's AWESOME!!!! GO GOO GOO DOLLS!!! WHOOO)

Oh, and an OC takes major part in this. If you don't like OCs, I beg of thee, give her a chance! I mean, it's Romeo and Juliet after all.

Two households, both alike in dignity,
(In far Verona, where we lay our scene),
From ancient grudge break to new mutiny,

Where civil blood makes civil hands unclean.
From forth the fatal loins of these two foes
A pair of star-crossed lovers take their life;

Whose misadventured piteous overthrows
Doth with their death bury their parents' strife.
The fearful passage of their death-marked love
And the continuance of their parents' rage,
Which, but their children's end, naught could remove,
Is now the two hours' traffic of our stage;
The which, if you with patient ears attend,
What here shall miss, our toil shall strive to men.

Seto Kaiba grumbled and finished reading the above passage out loud. He looked up at the teacher with an icy stare, who had made him read aloud the introduction to Romeo and Juliet, a book he cared naught for. And besides, someone had scratched out the word Verona and replaced it with Domino. Very clever, Someone, you know where you live.

"Thank you, Kaiba," the teacher said, trying not to shrink away from his stare. Ms. Dawson wrenched her eyes away from the sapphire icicles and looked at the rest of the class. "I wanted you all to hear that passage before we officially enter the Romeo and Juliet unit. Now, here's a question: Who here believes in love at first sight?"

The class shifted awkwardly, and a couple of people raised their hands. One girl raised her hand confidently. Kaiba smirked to himself. She probably had her mind warped by fairytales.

Ms. Dawson turned towards the aforementioned girl. "Iris, why do you believe in love at first sight?"

The girl blushed slightly, turning her cheeks a rich rose. "Well," she started hesitantly, "think about it. Wouldn't it be just a beautiful thing to love someone that much with only a glance?"

"You're thinking of lust at first sight," Kaiba cut in, smirking.

"You have yet to do even that, Moneybags," Joey retorted snidely.

"Wanna say that again?" Kaiba replied harshly, flashing a glare as cold as dry ice. Joey suppressed a shiver.

"Class!" Ms. Dawson cried out, exasperated. This happened almost everyday in this period! Why again did she leave America to teach a normal English Class to Japanese students!?

Oh yeah, she got fired from her first one, and this one offered to pay her more than her first job.

"Quiet down, you two," she snapped to Kaiba and Joey. "Or do I have to give you both detentions?"

Kaiba smirked and leaned back into his chair, his arms crossed. He said nothing. Joey growled to himself and also didn't reply.

"Since you're so supportive of debates today," she said to Kaiba, "give your reply to Iris Thorton's argument."

"Hn." Kaiba made a sound at the back of his throat that was something like a short chuckle. He leaned forward. "Think about it," he started, stressing the three words to remind the class that he was mocking the other student. He directed his reply towards Iris herself. "You see this really hot guy at a party, per se. You know nothing about him, and when he looks at you, he knows nothing about you, but takes a liking to your appearance. Is that love or lust? Love only comes from knowing the other person. Lust is being drawn towards their face."

"What makes you the guru of love?" Iris retorted after a long, held pause. But her retort was too late; the words have already sunk into people's skulls, and it was totally useless. Her face heated up and she stopped talking.

Kassandra loved hosting parties. So, that same day, she used the Romeo and Juliet unit as an excuse to host an early Halloween costume party, with a Shakespeare twist. She also spread a rumor that if you came to her party, two people will fall in love. The blonde told everyone that it could be you as she handed out invitations.

She even handed Seto Kaiba one. He had half a mind to just toss it in the recycle bin on his way out, but for some reason he shoved it in his backpack. Maybe it was a bout of laziness, but who knows.

So he brought his bag home only to have Mokuba ruffle through it in curiosity and read it, enticed by the bright graphics. And he somehow convinced his older brother to dress up and go.

That's how Seto Kaiba found himself in a Phantom of the Opera costume, with a long black cape, a dashing black outfit, and a white mask covering all but his mouth. He didn't want the half face one, because then he'd be recognizable, he thought dryly. He used hair gel to slick back his hair, dyed black with temporary hair dye. He looked at himself in the mirror before nodding in approval before heading out. With a mask and a different hairstyle, he looked almost unrecognizable. His blue eyes glimmered dangerously behind the mask, and he swept his cape around him as he turned and strode from his mansion, but not before snatching a red rose.

Kassandra's house was on the other side of Domino City, so Seto Kaiba had one of his employees drive him there. When his sleek black car pulled up to the address, many teenagers were already there. He snorted at how big the turnout was, and still more cars were arriving. Everyone was in full costume. They had all probably rushed out to the nearest costume store and gotten something sexy and mysterious. There were black angels, white devils, Victorian suits and masks, vampire gowns, faces painted pale and faces decked out in makeup. A lot of people wore masks, actually. Kaiba definitely didn't stick out much.

Kassandra was greeting all of her guests, dressed in an old ball gown with a pretty hat with a plume and a glittery purple cat-eye mask. "Welcome gentlemen. Ladies that have their toes unplagued with corns will dance around with you. – Ah, my mistresses, which of you all will now deny to dance? She that coyly refuses, she, I'll swear, hath corns. Have I hit close to home?" On she went, acting like she was Lord Capulet's lady counterpart in the party scene. But when Seto Kaiba stepped up to the doorway, the room fell silent under his frown and mask.

Now, while he changed his hair and donned a mask, he did not change his height. He towered over the majority of the girls, and some of the guys, too. So the girls were wondering, "Who are you, Mr. Tall, Dark, and Handsome?" and the guys were thinking, "Who the hell are you, Mr. Tall, Dark, and Possible-Girl-Stealer?" Kaiba smirked slightly when he noticed no one recognized him. He nodded politely to Kassandra, who immediately resumed her chattering, and moved into the house. The party resumed as it had before. Snippets of conversation floated towards his ears, stuff about how hot "she" looked tonight, and how the music was loud but good, how the food was delicious, how they wished they could do spin the bottle so that the hormones could cool down.

Seto Kaiba the Phantom drifted into the basement, where the heart of the party was. In one corner, a stereo was hooked up to a sound system that was wired into the basement ceiling. On another side of the room, a long snack table stretched from end to end, covered in delightful bits such as a red punch bowl, cheese and ham cubes, crackers, tortilla chips and salsa, popcorn, candy corn, licorice and Swedish Fish, etc. Soft flame-shaped lights lined the walls like torches, making the lighting comfortably dim and romantic. The kids down here were laughing, singing along with the music loudly, dancing, and having a good time. Kaiba leaned against the wall and watched the busybodies.

A softer song with folk roots started playing. The teens groaned light-heartedly and picked partners to dance with. One girl didn't have one, and thus started to twirl in the center of the room with not a care in the world. She was wearing a gypsy-style outfit, with a long dusty red skirt with golden yellow designs on the bottom and a short, matching top with only one strap. Between the shirt and skirt was a translucent scarlet cloth, covering-but-not-really-covering her midriff. The same material formed long billowy sleeves that started on her triceps and ended at her wrist. She also had a piece of that cloth covering her mouth and nose, hooking at her ears. Her honey-colored hair was done up in a high bun with two chunks of hair left deliberately out to frame her face. She wore a thing on her forehead that was made of gold spikes and a red gem in the center, traveling all around her head to clasp in the back. She wore a lot of eye make-up, making her amber eyes pop, and she wore gold sandals on her feet.

A guy dressed in a black and gold medieval prince's costume came forward and took her hand. She blushed coyly and agreed to dance with him. Seto Kaiba watched them aimlessly, reminding him of something pleasant. And then, she looked up into the Phantom's blue eyes.

It was a peculiar feeling, no doubt, that came over him in that brief moment. It was completely foreign, yet strangely familiar. It sent a shiver down his spine, yet it settled warm fuzzies in his heart. In that short few seconds, time slowed to a crawl. Something, some emotion, entered him and made his heart flutter against his ribcage. Sweet venom, poisonous honey, it bled through his veins and arteries, and he took in a sharp breath. Those amber eyes said made him feel something that no one else, nothing else save for Mokuba, could make him feel. And then he knew what it was, this sensation.

He had fallen in love at first sight.

He cursed silently for being such a hypocrite, but he whispered out loud, quoting Romeo and Juliet, "O, she doth teach the torches to burn bright. Beauty too rich for use, for earth too dear. So shows a snowy dove trooping with crows as yonder lady o'er her fellows shows. Did my heart love till now? Forswear it, sight, For I never saw a true beauty until this night."

Near him, with his friend in a Caesar outfit and him in a Brutus one, Joey Wheeler heard Kaiba's voice. It was too low for him to distinguish any words, but he recognized that voice anywhere. He said to Yugi, "Moneybags is here, he's bound to ruin everything! We should go stop him."

"Relax, Joey," Yugi said quickly. "Kaiba's not that type of person. At least not for parties. I don't think he's going to do anything tonight."

"But Yugi…" Joey protested.

"Shush," Yugi interrupted. "Let's go upstairs, before you ruin the party." That being said, Yugi pushed his friend up the stairs to the other half of the festivity. The song ended soon after that, and the Prince and the honey-haired girl broke apart and disappeared into the scattering crowd. The Phantom watched her carefully, secretly glad that she and the Prince were going separate ways. He snuck around the edge of the crowd until he caught her approaching the snack table. He grabbed her hand and pulled her away from the punch bowl to the side of the crowd, as far away from prying eyes as he could get.

"What's this that takes my hand?" she asked, surprised. She looked up to see determined sapphire eyes behind a white mask. She remembered them from a few moments earlier, and her heart fluttered giddily. She had seen him when she was dancing, and had immediately been captivated. Love at first sight, could it really exist?

"My unworthy hand holds this holy shrine, too ugly for this beauty," softly said the Phantom.

"Good sir, you do wrong your hand too much," sweetly replied the Gypsy. "For saints have hands that pilgrims' hands do touch."

The Phantom smiled softly and dropped his hands. "I feel like we're quoting Romeo and Juliet, some cheesy play or movie."

The Gypsy smiled back at the stranger. "Real life can be cheesy too," she said. "Sometimes those are the best parts, because cheesiness has happy endings."

"Is that so?" he mused. They locked fingers, holding hands palm to palm. They swayed to the music for a little bit before the Phantom bent down, pulled down the cloth covering her mouth, and brushed his smooth lips against hers. "And thus with a kiss, my sin is purged."

She saw where this was going, and replied lightly, "and I receive your sin."

He smiled slightly and said, "That can't be it, let me have my sin again," and he pressed his lips against hers again.

Kassandra came down the stairs and stood on the last step. "Hey, everyone!" she shouted, her blonde curls bouncing. Everyone looked up at her. "Karaoke upstairs! Come one, come all!" The crowd cheered and started streaming upstairs.

Another girl, presumably a friend of hers, pulled the Gypsy away from the Phantom, saying, "Let's go, Isis, karaoke sounds like fun!" The Gypsy looked at her friend and nodded, glancing back behind her with a question in her eye at the Phantom. The question was easily readable. Who are you?

The Phantom winked, but said nothing. Iris was pulled away, and she lost sight of him.

Kaiba stood there, thinking over his actions of the night. What had come over him? What had made him kiss that girl, Iris, who displeased him so? He thought of her face tonight, and pleasurable shivers shook his spin. There has definitely been a change of attitude on his part, but what made him do it? It seemed impossible that the tall, dark young man could ever love anyone apart from his little brother. And yet, here is a disguised girl who stole his heart with a single glance. O, what a hypocrite was he! An unbeliever in love at first sight, yet a victim all the same!

The basement was totally empty now, besides him. Everyone went upstairs to laugh and be merry with karaoke. He swept up the stairs and snuck outside without anyone noticing him. He blended into the night like a raven, his cape billowing out behind him as he headed home, lost in his thoughts.

He wasn't the only one lost in thoughts that night. Iris couldn't speak with curiosity. Who was the Phantom? Who was he that made her heart quiver with a glance? She imagined him from before, and she felt faint. She was dying to know. Her friend asked what was up, but she shook her head and walked away.

She found Joey and Yugi, and decided to ask them. She needed to find out, so maybe someone knew. She figured she'd start with the nicest people she knew.

"Hey, Yugi, Joey," she said shyly. The looked at her curiously.

"What's up?" Joey asked.

"W-well…" Iris started, poking her two index fingers together. "I need to know who this one guy was, 'cause he was wearing a mask and I'm dying to know his identity."

"Describe him," Yugi offered, "maybe we can help."

"Well, for one, he was wearing a white mask that covered all but his mouth…" Oh, his mouth! His lips were just perfect. "And he had a black cape and a red rose. Like Phantom of the Opera, ya know?"

Joey and Yugi shared glances. "You sure you got the right guy?" Joey asked incredulously.

"Yeah, who is he?" she pressed. Who? Who?

"Er, well," Joey stammered. "That was Seto Kaiba. But I don't think he wanted anyone to know he was here. I'd stay away from him if I were you."

Iris subconsciously put two fingers lightly on her lips. "Oh crud, my only love born from my only hate! Too early unseen, known too late!"

"Iris, what are you talking about?" Yugi inquired.

"O-oh, nothing," Iris said hurriedly. With an eagerness to get away, she pushed through the crowd to the outside world. She slid out of her sandals so that she could run faster. Tears from an unknown source started to spill from her lids, but she didn't wipe them away. How could she have let this happen? She shared not one, but two kisses with the coldest, cruelest guy in school. She stopped to catch her breath in the chilly October air and moaned, "I fell in love with someone completely opposite from me who doesn't even believe in love at first sight! Oh, that hypocrite! I bet he did it to tease me or something. But perhaps not…" She stopped and stood up straight. "He didn't look like he was false."

Warm hands suddenly grasped her arms, and she let out a short scream before the spun her around, and she could see a white mask glinting in the lamplight. Before she could catch herself, she gasped, "Seto Kaiba!"

The Phantom nodded and pulled his mask away from his face. His fair, sharp features glowed in the dim lighting as Iris felt her face grow warm with hot blood. Storm clouds boiled up ahead, letting a few warning drops fall before spilling the bucket.

"Yes, it's me," he said, tracing her arms until his hands held hers. A car with too-bright headlights drove by and briefly illuminated them.

"It's raining," she said softly before blushing even harder. God, how stupid could she be!? This guy was fooling with her mind.

In answer, Seto Kaiba pulled her under the line of trees. Moving her so that her back was at a tree trunk, he leaned down and kissed her. It was longer than the previous two, and Iris treasured the sweetness. O, his very scent excited her, and even as she closed her eyes against his blinding beauty, her heart squirmed happily.

He pulled away and whispered in her ear, "Love at first sight is still a lie, isn't it?"

"But it isn't first sight," she murmured back. "You've seen me all year so far."

He chuckled softly. "Yes, indeed." A sleek black car arrived at the curb and a man stepped out. Kaiba recognized him immediately, and said to her "I have to go. That's my driver."

Iris nodded and watched him sprint towards the man. She tried to think about what she knew about him, but all she got was the magic and the mystery.

His hair was already much browner when he stooped into the car, the dye washing out in the rain. He sighed contentedly in the back seat. His driver looked at him in the review mirror. "Did you have a nice time, Mr. Kaiba?" he asked cautiously.

Kaiba stared out the window. He said, almost inaudibly, "You can only imagine."

End of Act 1

Well, it was GOING to be a oneshot, but it got so long, I'm making it a twoshot. I might make a slightly different one that uses mostly the actual cast of characters from Yugioh, but Iris was already made and handy, and thanks for giving her a shot!
