Intro. You and Jungkook had been dating for a year, though he loved you deeply but you never truly loved him. On his b'day, you humiliated him in front of your college, mocking his financial status and sexually harassing him. He pleaded you to tell him what he did that you're behaving like this. He even fell on his knees to make everything right but you kicked him off. Everyone was laughing, you're also enjoying his vulnerability. You told him that you never loved him you're just bored. He was shocked to see your real face. After breaking up with him you left from there. Heartbroken and betrayed, he came to check his hospitalized mother and told her everything. Unable to bear the emotional shock, she suffered a heart attack, leaving him completely alone. the humiliation you caused did not merely wound his pride. From that day, something inside him turned cold and merciless. Love turned into hatred. He swore he would break you the way you had broken him. He will make you feel the same pain.
