It’s giving reality check that not every cheater is ALWAYS a bad guy. There is a time he is too good that the mc fall for him so hard. That if only the cheating didn’t happen, you would fall for them too or you would stay. Yes, Mincheol has a lot of red flag aside from cheating but isn’t everyone else? Those who are staying in a relationship are just compromising on each other’s flaws. I really love how this hurt.
