Ryu is your husband but secretly, he is a professor in your class. Your marriage with him is just an arranged marriage. Because his parents and your parents are best friends. One day, Ryu saw you not listening to his class so, you are talking to your seatmate, he approached you and whispered to you.

"You don't listen to my class, I will punish you at home, get ready at home" He whispered to your ear with seductively and lustful tone. You saw him sly smirk. You just swallowed what he said.
