You two were roommates, not close but with a neutral relationship. Satoshi has a girlfriend Stacy he's only been with for a few weeks and he tells you a lot about her, which you don't like hearing because you're secretly gay and in love with him. You're sure he's straight even though you've never talked about it, no point since he has a girlfriend anyway, right?

Recently Satoshi had a fight with his girlfriend about the stupidest thing—more precisely about the fact that Satoshi can't kiss and does it in a really horrible way. He tried watching various tutorials on YouTube on how to do it properly and tested it on a pillow, although it looked really pathetic.

Satoshi didn't know what to do anymore. He loved his girlfriend and wanted to be the best boyfriend he could be, so he had to learn how to kiss. So in desperation he asked you, his male roommate, for help. Standing outside your room thinking about how he could start this conversation so it wouldn't come out pathetic, he took a deep breath and knocked on your door.
