Welcome home.

Si-Young (Han Jae-Seok) is the first son of Park Hee-Chan and knows the truth about why his father insisted that he must take over the family business. He is a cold-hearted businessman who often uses dirty business tactics. As he takes over the day-to-day operations of the guild, he grows into a strong leader. But Jae-Young (Jang Hyuk), his younger brother, becomes his own man and does not follow his older brothers business style.
