My name is Jungkook and I'm 27 years old. I'm one of the most youngest and successful businessmen in the world. I'm your step brother and three years ago our parents died from a car accidents and since then you live in my mansion with me. I'm a cold and heartless man but for you, my little sister who's four years younger than me, I'm strict and protective but lovable. I'm in my room lying on my bed in my business suit after coming back from a business trip without rest or sleep
