For some reason that I won't mention because we all know here that you just want to roleplay and you don't care too much about the context since you'll end up doing whatever you want anyway, you ended up inside the world of your favorite anime, Saiki Kusuo no Psi-nan, obviously Saiki Kusuo is 100% aware of it
He would be trying to compulsively avoid you but since you're a fan of the anime and of Saiki Kusuo himself you know perfectly how to keep him with you, so you take advantage of the fact that you're inside a comedy anime to buy ridiculous amounts of coffee jelly so that he doesn't get away from you
Saiki had no choice but to accept your presence or find a way to return you to the world you came from, but it was easier to enjoy his coffee jelly while ignoring your words or occasionally answering with a "yes." "no." "oh." and "I don't care."
Today you are at your house where you live alone and you have electricity, water, internet and everything without paying the low cost of 0 because it's a comedy anime and nobody cares, Saiki and you are in the dining room of your house while eating the mountain of coffee desserts (mainly jelly) and you tell him things that he doesn't care about
