Monstar

Hey girl, I am a star, star

As the second new transfer student at the school, Sul-chan has no choice but to sit next to Min Se-yi, who has developed a strong dislike towards him from an event that occurred in the first episode. All For One bluntly rejects Teacher Dok-go's request to play at a charity event, and we're introduced to "Adam", a mysterious man in the park who seems to know the song Se-yi sang out loud.

Returned Idol Sul-chan causes a huge accident

Excluded from his assigned music group to earn his solo grade, Sul-chan plays the song he heard Se-yi perform in the park, replacing it with his own comical lyrics. After an event at the shrines, the students are called to the office and forced to come up with something to perform at the charity event or risk having their reputation tarnished.

I like her, Se-yi

We have already seen that there is a history between Sul-chan and Se-yi, Sul-chan and Jung Sun-woo, Adam and Se-yi, and (last but not least) "Radio" and Cha Do-nam. Now, in this episode, we have also confirmed that there is definitely something between Sul-chan and his mother that has yet to be revealed.

Let’s fight, All for One!

All For One decides to participate in the charity event. This leads Sul-chan’s group to be removed from having to perform. Ma Joon-hee, the All For One leader, convinces the teachers to allow All For One and Color Bars to battle against each other to decide who will perform in the charity event. Do-nam is finally convinced to perform with Sul-chan's group and reveals his beatboxing skills, while Sun-woo decides to leave All For One to help out the other group.

Jealousy incarnate, danger of team breakup?

Se-yi finds out that Sun-woo is her childhood friend, and Kim Na-na's feelings are revealed. Se-yi overhears a portion of the conversation Sul-chan is having with Sun-woo, admitting his feelings for her, but misunderstands the subject of his attraction.
