Wait if there's no chemistry between the mcs then how is besoo the problem? He has his own love interest right (which i personally think is better than the main love story) The main characters are kinda trash period. I feel like heesoo is the one who had the most character development no?
Heesoo was the one who offer money to uke to break up and then after he give birth he help uke to run off. Heesoo knew seme love uke but he was so selfish that he act as a bridge between them. That's not very kind.
Good fro him he live happily after but what he did was literally the plot of mc so yeah he was the bad guy.
Just finished reading it and ive figured it out heesoo is the problem. He's the reason why there's no chemestry between mc. Ugh I hate both mc their behaviour is so frustrating.
