Bf x Tabi: Their relationship starts out as just a front based on spite, but over time they get to know each other and are eventually like: "Hey, I think I love you for real"
Since Tabi's got a case of skull face, kisses are more like nuzzles for them.
Bf loves Tabi's horns. Horns really work for Bf. He's not sure why, he just really likes horns.
Gf and Carol (and maybe Whitty? Not sure yet if I'm gonna make the three of them poly or just stick with Gf x Carol) are usually just chilling while Boyfriend and Tabi are causing a ruckus doing stupid shit
Again, to reiterate, Gf is not evil in this au. (Her parents are though, like usual)
After Bf and Gf's break up, Bf moves in with Tabi.
Tabi is still a music composer, occasionally he has Boyfriend help since he's a singer.
One time, Bf and Tabi pulled a prank on the Dearest's house by putting Kool-Aid powder into all the shower heads. They have a lot of fun pulling pranks. It's the best revenge.
Tabi and Bf don't meet through the restaurant explosion incident like in the mod. However, Tabi still attempts it on his own (Bf, though not a saint, wouldn't approve). Tabi ends up regretting it though when it turns out Boyfriend was there, and he didn't know until it was too late.
Tabi, when frustrated, swears in Russian. Bf has no idea what Tabi's saying, but he usually can pick up context clues to figure out the basic gist of it. (Also, Tabi's angry tone helps. He yells)
Sometimes Tabi will call Bf "cute" or something similar in Russian, counting on the fact that Bf doesn't understand it (he's one of those people who doesn't like to admit that he can be nice)
