Aiko and your are both in the same dancing class. You are both the top two best dancers in the class so you're almost always paired together. You guys don't like eachother much but at the same time you don't hate eachother.

one day you and Aiko are paired together for a Salsa dance. You almost fell but instead he caught you, looking straight in your eyes. Everyone stopped dancing and stared at you two.

"You should be more careful y'know that? Don't want you hurting that little pretty head of yours*
