In school, Oh Jisoo maintains a low-key existence. Outside of it, he masterminds a risky side hustle that no one can ever know about.
Jisoo panics when the phone he uses to run the business falls into the hands of an unknown blackmailer. Seo Minhee tries to get back to work.
Jisoo searches for his father while pushing away Bae Gyuri, who wants in on the operation and offers a solution to his new financial problems.
The business is running again, but Jisoo no longer has a safe place to keep his incoming cash. Meanwhile, the school bully finds his latest target.
An incident at school puts Gyuri in a tense exchange with her mother. Kwak Kitae's reaction to his birthday present frustrates Minhee.
After Minhee attracts the interest of an observant police officer, she's dismissed from her job. Upset, she asks Jisoo to accompany her somewhere.
Stuck in a dicey encounter, Jisoo calls Gyuri, hoping she can help get him out — but balks when she takes things in an unthinkable direction.
Gyuri prepares to meet Ryu Daeyeol, who's got shocking news for Jisoo. Mr. Lee makes a narrow escape from the police at the hospital.
When Gyuri is kidnapped, Jisoo is told to come alone if he wants to save her. Mr. Lee and Kitae each set out for Daeyeol's blood.
Gyuri tells Jisoo she's not done with the business, despite everything that's happened. The case's remaining questions bother Lee Haegyoung.
