The man with the wife is the MC's brother. The MC is in love with the wife. The wife and the MC's brother had a child together. But because MC has feelings for the wife he couldn't even look at the child (his nephew).
Seeing the child probably pushed MC over the edge so he got drunk and agreed to have sex with Jinhee.
I’m so confused who’s related to who?! Who is the mc in love with?
