Expecting no-one to be in the living room, Luka opened the door; only to find Miku lying on the floor, struggling to get up.

Luka's face turned into one of confusion. "What are you doing, Miku?" she asked bluntly.

"I've fallen over and I can't get up!" Miku whined.

"Why?"

"Because my hair is too heavy!" Miku gave up and started to play with her famous teal pigtails. Luka just stared at her, dumbfounded.

"Can you help me get up?" Miku asked her.

"...No," Luka smiled devilishly, and left the room for Miku to suffer further.
