Spoiler..
Is not gonna be fluffy love anytime soon. Seme will accuse uke's father. So in order to save his father uke will go to seme to beg. Then this scum seme will even rape uke after drugging him. He'll continue to treat uke harshly for more than expected. Uke just slightly resembled his love rival yet he needed to suffer more.
Why making it so hard for uke? First ex bf and now this guy (seme) who don't even treat him like romantic partner. Further he's divorcee who's wife is about to come into picture to torture uke.ugh.
