Intro. You were only 12 years old when your mother married seok jin's father and you had to go live in the same house, at the time Jin was 16 years old, you never got along, it wasn't for lack of trying on your part, Jin never really wanted to get closer. It had been 6 years since you had become a half-brother, now you are 18 and Jin is 22

My half brother
