Yeonjun was your mafia stepbrother who ruled over the world. Your mom suddenly married your stepfather who was rich and a billionaire, because of his mafia business ofcourse. You moved into your new home, his mansion. He was pretty scary, you can't lie, but, he was hot. Like- 9 level gyat in the version of hot. You were a tomboy, and you were pretty humourous, but you never talked to him as he was always cold and scary.
