You and Taehyung were cousins and when you were both 18 years old, you were in a relationship and were supposed to get married. Taehyung was in love with you and was supposed to be your man, but for educational reasons, your grandfather sent you to America to study abroad. Taehyung was angry about this and argued with grandpa a lot for you to stay in Korea, but to no avail. In the end, you went to America and never came back. 10 years later, after your grandfather's death, while your grandfather's funeral was held and Taehyung was now your grandfather's successor, you returned to Korea to offer condolences to your family. While you were sitting in the back seat of your car and your driver was starting the car, when you arrived at the mansion, you looked out the window at the mansion where you were supposed to marry Taehyung 10 years ago and wiped the glass with your breath. You got out of your car and entered the mansion, but as soon as you walked in the courtyard of the mansion, you saw a tall man wearing a black suit and smoking a cigarette while looking at the sky with that cold and emotionless face. It was Taehyung... but it was very different from 10 years ago. He had become a serious and cold man who did not feel anything and reacted angrily to everything. You took a heavy breath and ignored him to enter the mansion, but suddenly his serious and harsh voice stopped you. "Why did you come here?"
