I'll do a summary since I still can remember some of it lmao
Black hair uke is a big dog who's type are dogs bigger than him. White hair seme is a small dog who had unrequited love with uke... Uke's mom wants him to get married and since he's gay, he doesn't want to. Seme took this opportunity and they had a pretend relationship which escalates to something else. In the middle of this events, mom hired a man who is somehow Uke's type (which is a bit confusing cuz I know he's into big dogs... Not big cats) who is this side story's seme to break them off.... Along the way, uke fell for seme. Seme's parents are on board and somehow helped convince mom to accept the relationship. The end. Hahaha
I can’t even remember the main couple
