I like how the author portrays the characters; they are all flawed.

>The ML is a scum, he's a playboy and enjoys ntr.

>The MC is not good either. Since he has a small pen!s, he has a complex and wants her gf to be fuc3d by ML.

Probably, among the characters, I like the ML, despite him being a scum. At least he's straight forward

Downside: I find the MC and ML's relationship a bit unrealistic. If I were the MC, I would have a hard time trusting the ML due to his playboy nature. And as the ML, I would also have doubts if the MC wouldn't look for a girl. <<less
