Su Ho goes all the way to meet Ju Kyung late at night with a lame excuse. Ju Kyung starts to wonder if Su Ho has feelings for her. She asks him out. Meanwhile, a first-year student is bullied by her classmates for her ugly looks. This reminds Ju Kyung of her past school life and she decides to offer help.

Su Ho’s father visits Saebom High School to meet Su Ho’s teacher. Everyone at school gets surprised by the fact that Su Ho’s father is actor Lee Joo Hun. Meanwhile, Ju Kyung runs into the bullies who used to harass her before transferring to Saebom High School. Su Ho happens to see them and decides to help Ju Kyung.

Ju Kyung’s heart doesn’t seem to calm down whenever she sees Su Ho. Unfortunately, she finds out that there is already someone whom Su Ho likes. Devastated and disappointed, Ju Kyung begins to naturally avoid him. Meanwhile, Hyung Jin, the ace baseball player from Seonil High, confesses his feelings to Ju Kyung.

The students of Saebom High School go on a school trip. Su Ho makes up his mind to tell Ju Kyung that he has feelings for her and even buys jewellery for her. However, Ju Kyung gets heartbroken, thinking that Su Ho likes Soo Jin. Meanwhile, Hee Kyung gets transferred to a different department at work without prior notice.

Not long after reassuring each other’s feelings, Ju Kyung and Su Ho initiate a movie-like plan to keep their relationship secret at school. However, doing so makes it difficult for them to enjoy a typical ordinary date. Su Ho even puts up with embarrassing moments for Ju Kyung. Meanwhile, Seo Jun is having trouble getting over Ju Kyung when he bumps into her at the least expected place.

Ju Kyung still doesn’t want to let her friends know that her boyfriend is Su Ho. Soo Jin tells Ju Kyung that she plans to tell Su Ho that she has feelings for him. Ju Kyung gets torn between love and friendship. Meanwhile, Su Ho and Seo Jun happen to meet at Ju Kyung’s house and start to make dumplings with Ju Kyung’s family.

At school, Su Ho comes back to his class, and Ju Kyung runs into Hye Min who just transferred. Hye Min asks Ju Kyung if they know each other, but Ju Kyung denies and keeps avoiding her at school. Meanwhile, Soo Jin and Se Mi make a deal, and Se Mi shares with Soo Jin the photos of Ju Kyung without makeup on her face.

A video of Ju Kyung sends the whole school in turmoil. When Ju Kyung finds out that her past from the old school has been exposed, she runs away. However, it doesn’t bother Su Ho a bit what others are saying. The only thing that worries him is whether Ju Kyung is okay or not. Meanwhile, Seo Jun does whatever he can to get to the bottom of this happening and is shocked when he finds the person responsible for the video.

Ju Kyung comes back to school and makes up with Soo Ah. Everyone at school finally finds out that Soo Jin was the one who uploaded the photos and videos of Ju Kyung being bullied. Meanwhile, Soo Ho and Ju Kyung go on a trip to the sea, but Su Ho forgets to bring his cell phone. Seo Jun desperately tries to reach Su Ho.

Ju Kyung and Su Ho have no other option but to accept the breakup. After, Ju Kyung stumbles upon the fact that Su Ho is the very boy she met at the Prince Comics when she was young and struggles even more. Meanwhile, Seo Jun finds it difficult to hide feelings towards Ju Kyung and decides to act upon it. Confused by Seo Jun’s unexpected confession, Ju Kyung heads out to Namsan where she bumps into someone.
