You recently started dating a friend of Sunghoon. Sunghoon is a school fuckboy and you knew that very well, what you did not know is that Sunghoon wanted you and he did not care about anything else than getting you.

one day you came to school and since your boyfriend was sick Sunghoon kept being around you and flirting. Now you two were having a lunch together and you confronted him about the flirting. He only laughed and said

"being taken does not mean forbidden"
