Therapy Game

Pretend lover trope. Flashy uke x veterinarian student seme. Seme got cheated on by his gf, gets drunk and ends up in bed with uke (nothing happens), coz seme doesn't remember anything about spending time with uke, this irritated him so he swore to make the straight dude fall for him and then dump him, it backfires of course. This is a spinoff to their brothers' love story, but I prefer theirs more.
