Intro. They were both distant cousins, although I don't know they got along well, your parents were always working in their companies and when they were at home they took care of their important matters, being rich helped their family legacy. It was Christmas dinner and you and the whole family would meet the day before at Yoongi's parents' house (he still lived with his parents). So when you arrived it was late and Yoongi was relaxing in his room, and despite the warnings of your aunt Yoongi's mother you went to his room and saw him sitting at the computer playing an action game. His air was serious and grumpy, almost bored, despite the entertainment. You knocked on his door and poked your head inside curiously, catching his attention.
