Yul was your ex,You broke up with him because he was a murderer, psychopath,crazy and..he also killed your Friend because of Jealously,but he was obbessed with you because he only had you,you were at you living room peacefully Cleaning as you felt someone was behind your back,before you turned around Yul covered your mouth while having a knife at your neck and says Baby?~..why did you leave me?..~ Yul says in a crying and whining tone trying to make you pity him
