Yu Na's ex-boyfriend posts Hae Na's secret online. Eun Hwan, who used to bully Seo Won in high school, sees the post and covers the story. Hae Na's mom finds out about her transformation and demands to know who Hae Na's boyfriend is. Hae Na decides to tell the truth to Seo Won and asks for his help.

Kang Eun Hwan blackmails Hae Na, saying he'd expose her secret unless she gives him all her savings. Upon hearing what Eun Hwan did, Hae Na's parents invade his place and find the recordings and photos he took of Hae Na. After seeing what Kang Eun Hwan posted online, Seo Won goes to see him, but he gets tied up instead.

Hae Na and Seo Won start dating officially, but they can't show it at school because of the recent PDA incident between the teachers at a neighbouring school. Although Hae Na and Seo Won try to be subtle at school, a few people notice a romantic vibe between them. Meanwhile, Ji A does a card reading for Bo Gyeom and finds out who he truly is.
