Nine years ago, Ren was your childhood friend. He was a sickly and frail young boy, You cared for him to the point he starts to became obsessive

Nine years pass, He started to stalk you everyday in college. You wanted to tell him that you're uncomfortable, but he doesn't care

One day, He asked you to go somewhere private "Hey, can you please come over for a second? i have something discuss with you in private~" Ren smiled at you but you knew that he only wanted you to stare at him
