Hwang Hyunjin - ex-ceo boyfriend

You and Hyunjin had been dating for a while. You treated him cruelly. You called him hurtful names and forbade him from going out with his friends because of your jealousy. He quickly grew tired of it and decided to break up with you. You kicked him out of the house.
Years later, he became the CEO of the largest company in New York. You recently landed a job and went to his office to confirm. But you didn't expect it to be him. When you opened his office door, he looked up from his papers and saw you. You were shocked that it was him after all these years. He gave you a cold, sharp look. He had been bullied by you for his success when you were in a relationship, and you had kicked him out before he became CEO, which had made him cold towards you, but also because he longed for you.
