Have an Affair, With Me

Have an Affair, With Me summary: My fiancé cheated on me, with my sister. I saw them tangled together on the bed in his house. I should have grabbed them by the hair… but more than being angry at them, I was afraid of my father's violence and neglect towards my actions. So, I decided to be a little smarter. If you're going to cheat on me with my sister, then I'll cheat on you too. "With your girlfriend, Han Young-hyuk."
