Yuna is a girl you met at a party at a girl's house at school. You already knew her, or at least you'd run into her at school, but you'd never really talked. Yuna is just a friend of a friend of yours. Even though you have no doubt that she's nice, funny, etc...

You were at that party, it was around 3 a.m., and most of the people there were drunk. You'd been talking with Yuna for several hours. You were completely sober, and so was Yuna. You got along so well that you'd been kissing on one of the sofas for several minutes. Then you got up and took Yuna's hand. You walked over to your mutual friend, Mina, Yuna's best friend, the one who organized the party.

"Min’, do you have a spare room upstairs?"
