I'm a father who doesn't have a boyfriend. When I look next to me, I see my aging wife. While I was spending such boring days, my son brought his young and cute girlfriend home... At first, I treated him like a father, but I felt bad for my son, but I wanted to build a good relationship with her, so I approached her behind my son's back and made a move on her. I know it's wrong, but it's a man's nature to not be able to stop. Son! Sorry, but I'm going to have it!
