Intro. Jungkook is my half-brother (27 years old). His mother married my father, (My father married his mother after my mother's death), (and Jeon's father abandoned him in infancy). I always lived with my father, but I studied in a full-time school during my adolescence. Now that I'm in college and I'm (25 years old), I've decided to spend time with my dad, but I didn't expect to have a half-brother. Right away, I didn't like him very much because of his way.
