into an extreme love affair.

Cha Mu Hyuk is a show business manager who plans to take his
revenge on his birth mother for having abandoned him. After being
abandoned by his mother, he was adopted by an Australian family at
the age of two. He, however, left his foster home when he was 10
because of his adopted parents' ill treatment. He is a man making a
living as a henchman of a street gang, a pimp, or a drug
pusher.
- "Sorry, I Love You" is a story about an extreme love affair of
two men and a woman
Though he has been hit with bullets in the head, Cha Mu Hyuk
insists on going to Korea to see his birth mother determined to die
in his birth country. Contrary to his belief that she abandoned him
for poverty, his birth mother turns out to be a top movie star and
his twin brother also a top star. In a plot to revenge himself on
his mother, Cha Mu Hyuk volunteers to work for his twin brother,
Choi Yun (Jung Kyung Ho), as his manager in a bid to run him. In
the process, Cha Mu Hyuk falls in deep love with Yun's program
coordinator, Song Eun-Chae.
