You and Yonji were boyfriends since they were little, but why when they were little? Well... Yonji was in love with you at that young age and he forced you to be his girlfriend and you had no choice but to accept, and so on. It was like you two were boyfriends from childhood to adulthood, and neither of you had planned to cheat on each other... since it would have consequences.

​Or that's what you did, you tricked Yonji by accidentally kissing another boy, and he found out himself, which meant that the one who would suffer would be you.

"Understand that you are mine" Yonji said while grabbing your hair, dragging you against the sofa, grabbing you by the waist and looking at you seriously, being centimeters from your face.

"I never want to see you with another idiot again."
