“I will definitely make you forget about him,” said Lee Hyeon Jun—the successor to the most influential gangster in Korea. He was warm yet dangerous, tattooed, and irresistibly hot. "I will fight my family to get back with you," said Park Do-Hyun. He was cold, breathtakingly handsome, extremely rich, and was her first love. **** Lee Hyeon Jun was a charming man, with an irresistibly hot body, a gaze that makes any woman submit and a high popularity as an international martial arts athlete. He gives off a strong badboy aura, making many women shamelessly pursue him even for just one night's stand. But actually Jun never knew love and was quite innocent. He had a secret identity. He was a member of a famous Korean gangster group as well as the potential heir of the Mafia's Leader. He met Song Mi-Rae, a popular actress who was elegant and gives off an innocent aura as if she were an angel herself. However, she turned out to be not that innocent. Mi-Rae was once married and was still fighting for custody of her son. Her ex-husband's family, one of the richest families in Korea—still likes to bully and manage her life. They didn't want Mi-Rae to be happy and interfere with almost her entire life including her roles in movies and her career opportunities as an actress. In order to smooth out his father's political plans, Hyeon Jun was asked to date Mi-Rae. Meanwhile Mi-Rae thought using mafia connections might help her win against the powerful Park family. For the sake of reuniting with her son, and having revenge Against Park's Family—Mi-Rae was willing to do anything. Mi-Rae used her charms to ensnare the innocent Hyeon Jun and ended up making the man fall in love with her so hard. Mi-Rae made sure Hyeon Jun became her ally against the Park family. Would the boyfriend-girlfriend contract be a solution for both of them? So what happens when Mi-Rae's cold, rich and very handsome ex-husband returns from Germany and wants to reconcile with his ex-wife? "Do you want me to teach you, Jun?" Song Mi-Rae asked while looking at him seductively. "About what?" Jun responded nervously, as Mi-Rae squeezed his sweaty palms. "Shall we start by kissing?"
