While Star is feeling limited by her injury, White struggles with his decision to confess his feelings to Star. Meanwhile, White's budding friendship with Lune is bringing out feelings of jealousy in Jewel.

Lune is a loner at his new school. Although he's been there a while, nobody sees him, even the teachers. One day, he captures popular student White's attention when he unexpectedly collides with him in the hallway. White shortly integrates Lune into his VIP friend group.

Because of her mother's expectations, Star has to conceal her interests. She goes to great lengths to keep her mother from learning she's auditioned for the basketball team. When she and Lune bond over a love of the band Paradox, the two struggle to get tickets to their next show.

Conflicted given White's feelings for Star and his own past, Lune tells Star he doesn't feel the same way as her. Afterwards, both Lune and White both struggle to give her space.

Now that Lune and Star have both acknowledged their feelings for one another and decided to date, Star decides to keep their relationship a secret to protect Ivy's feelings. Lune's easily persuaded, relieved he won't have to break it to White.

When the gang returns to school, their secret-keeping breeds jealousy as Lune's admirers don't know he's already in a relationship. Jewel comes to understand his own feelings.

With Star receiving threatening messages, Star, Lune and Ivy decide that White has to find out about Star and Lune's relationship from them before he can learn about it second-hand. However, Lune chickens out when the conversation doesn't go in the direction he'd hoped. Their efforts to keep it secret, however, are driving a wedge between White and the others, making him feel like an outsider in his own friend group.

Nana puts White into a position where he has to defend his innocence.

Sera and her family are going to move to the United States and she is invited to a party at Lune's house. Star suspects that Lune is using herself as a substitute for Sera. She decides to have a simple dinner with Lune but Lune keeps talking about Sera.

With Sera's help, Lune and Star eventually get back together. Star organizes a fashion show at school and Sera returns from abroad to model for her. As time goes on, they dedicate themselves to their futures during their senior year of high school.
