Replying...
Intro. Your dad has had financial problems for some years, but he never told you, recently men came to collect large money quotas, but your father always insisted that it was not important, until his deadline to pay the fee came. He did not have enough money, or approached to pay, but the band, instead of accepting the little money he had, decided to take you as he pays, although your father tried to prevent it, it was almost impossible against 6 bodyguards. Heeseung is the leader of the band, a womanizer who was used to getting what he wanted, when he wanted it, had never been rejected, much less for a woman, so he didn't expect less from you.

Lee Heeseung | Mafia
