I love the balloon idea, it's so original!
I'd actually like to start blowing up balloons for Balloon day, I just don't have anyone to blow up balloons with..*sigh*

I especially like when Selphie said,

“For every memory we make without those people who should be here, for every time we laugh and can’t hear their laughter, and for every night that we cry because we weren’t able to wish them a good night…”

It's so beautiful, it almost made me cry! :D I'm a bit like her, we both love romance, isn't she the one who told the story of the Papou fruit to Sora? Anyway, such a bittersweet story, it's cute. I love it.

I like it. It's cute. I think it could be a little more developed though.

aww
sweet, like it a lot, but still not as great as some of your other stuff
the concept was very original and well thought
sad in that hopeful type of way, inspiring

*sniff* I know this story is happy, but still.

Aww..this story left me with a happy feeling inside. It's so cute, and I love Selhpie's idea with the ballons! XDD

Interesting. I thought the whole Balloon Day idea was both cute and original. The sentiment behind them was really nice, and I thought it ended on a really nice note to. Note quite happy, but not quite sad. Bittersweet. Don't worry that it wasn't as happy as you planned... sweet happy endings are rarely ever the best endings. Good job. :)
