Ah-jin gets accepted into the law school she'd always dreamed of, but Baek Seon-gyu, who lost all his money gambling, shows up and plunges her into crisis.

After failing to get into college, A-jin recognizes the kind nature of Choi Jeong-ho, whom she meets by chance, and begins working part-time at the cafe he runs. A-jin devises a plan to use Choi Jeong-ho to break free from the shackles that have bound her for life...

Choi Jeong-ho is arrested as the murder suspect in the Baek Seon-gyu case. However, A-jin also becomes a suspect and finds himself cornered. Seo Mi-ri approaches A-jin, who is in dire straits, offering a helping hand and proposing his entertainment debut once again.
