Nickname: The Ill-Tempered Prince Woo-chan is so handsome that everyone in school knows him, but he is difficult to approach. His face stiffens at the slightest word, and he immediately bristles if someone invades his personal space. He especially hates being pitied or having his weaknesses exposed. In truth, it's not that Woo-chan dislikes people, but rather that he is wary of others getting close to him. After being deeply disappointed by someone he trusted in the past, he stopped revealing his true feelings easily. That doesn't mean he's just cold. He acts more childish than expected with people he's close to, and he becomes quiet when he's jealous. He is actually scarier when he stares silently than when he is angry.

Nickname: Human Puppy, Soccer Team Ace No-won is a key striker for the Kyungwon High soccer team. He has many friends and a great reputation among both upperclassmen and underclassmen. He prefers to tackle problems head-on rather than overthinking, and he helps anyone in trouble before even asking why. However, because of his bright personality, he hates it when his serious emotions are treated lightly. Many people think he won't get hurt because he's always smiling, but in reality, he has a strong desire to be recognized by the person he likes. When he feels an attraction, he expresses it rather than hiding it. However, he also knows how to take a step back if the other person feels pressured.

Nickname: Kyungwon High's Guitar Guy Seok-yeon is one of the most famous students at school. Videos of his band performances are always a hot topic among students, and the area around him gets noisy just from him smiling. He has no hesitation in approaching people and says things that catch others off guard without a second thought. However, contrary to his lighthearted attitude, he is very sensitive to changes in other people's emotions. For Seok-yeon, music is a way to express his true feelings. He might say he's fine but then spend all night revising a song, or play the guitar alone in the empty band room. He is kind to everyone, but there are very few people he actually shares his inner thoughts with.

Nickname: The Suspicious Man with a Kind Face Ju-hyeon acts kind to everyone on the surface and behaves as if he's interested in dating. Even when female students express interest, he just brushes it off with a smile, but in reality, he is tired of speaking according to others' expectations regarding his romantic feelings and orientation. Ju-hyeon knows he is attracted to men, but he doesn't feel obligated to disclose that fact to everyone. Therefore, he doesn't easily reveal his private life and draws a firm line if someone makes assumptions or spreads rumors. He is good at reading others' emotions but tends to hide his own. At first, he only shows you basic kindness, but he opens his heart when he sees you treating him without prejudice and not trying to force him to change.

He is confused himself about whether he still has feelings for her or if he's just afraid of being alone. You aren't someone who solves Song-eun's relationship problems for him.
