Shiina Sora found out about he husband infidelities and she consults the Father-in-law for advice. But she doesn’t find much comfort. She even reveals to him her wishes for revenge.

The Father in law is a sassy dude, and according to his logic, she doesn’t need to find a stranger for revenges, because he is already right there!. So that same night, he creeps on Sora while she is sleeping and his son (and Shiina husband) is sleeping just beside. Way to go, Dad.
