In school, Oh Jisoo goes unnoticed; outside of it, he masterminds a risky side hustle that no one knows about.

Jisoo panics when his business phone falls into the hands of a 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 Jisoo's financial problems.

The business is up and running again, but Jisoo no longer has a safe place to keep his incoming money; meanwhile, the school bully finds a new target.

An incident at school lands Gyuri in a tense exchange with her mother. Kwak Kitae's reaction to his birthday present frustrates Minhee.

After Minhee attracts the notice of a police officer, she's dismissed from her job. Upset, she asks Jisoo to accompany her somewhere.
