Main Characters:
Hirai Momo
• A student who lacks academical intelligence due to an accident she've experienced back from when she was just a little kid. She struggles to pay close attention towards lessons and discussions at the academy, JYP University, she's currently attending in. Despite having enough money to enroll herself at such a prominent school, she couldn't maintain a good performance, leading her close towards her expulsion.
Chou Tzuyu
• An overall definition of perfection, as many people claims him to be. An intelligent, softhearted, and good-looking young man who seemed to be the envy of every other guys and an apple of the eye for the females. The catch? He's a depressed soul who yearns for the meaning of life. A guy under pressure, trying to keep his reputation intact for the sake of his family.
Minatozaki Sana
• An outgoing teen who loves to spend his time, either hanging out with his friends or with a different female student day after day. Known to be the player of the academy for his flirty behavior towards women. Little do they know, this was just an act to cover up his true feelings; his feelings towards his own best friend, Tzuyu- his one and only best friend since birth. They've been through thick and thin together up to the point wherein they much look like brothers to each other. Though, Sana doesn't really consider him as one.
Side Characters:
Im Nayeon
• The enthusiastic class president of section TWICE, the star section of the 2nd years. A close friend of Momo's that she already considers as her own sister. Formerly tutors Momo in middle school and in their first year of high school, as to why she had passed. Nayeon even helped her learn Korean when she was struggling with it. But now that they're in their second year of high school, Nayeon doesn't have time to tutor Momo anymore as she needed to focus on her own studies.
Yoo Kyungwan
• Also known as Yoo Jeongyeon, as addressed by his friends. A reckless yet also outgoing friend of Momo. Often misses the class, but makes up for it by voluntarily participating in school trips. A father-like figure to Momo due his responsible manner, despite being a troublemaker, and for always keeping her in a proper behavior, scolding Momo from time to time if it's a must.
Park Jihyo
• Mother figure not only to Momo, but to almost each and everyone of her friends. Swore to be on a one-sided rivalry between her and Momo due to her competitiveness in dance class back in middle school. But softened as soon as she found out that the Japanese's like a child who needs undivided guidance and attention.
Myoui Mina
• A good friend of Momo and Sana, unbeknownst to both of them. A sister to the former, and a person who plays along with each antics for the latter. Polite and respectful but also respected, for her father is a top surgeon in their home country as well as a board member ARO council and Japanese Society. However, she chose to be herself rather than boasting her fame; an introvert and bashful student who prefers to be alone most of her time.
Kim Dahyun
• One of Sana's closest friends and the only female student he cannot flirt with, except for when they first met. They often share each other's everyday life and updates. Dahyun's the only one whom Sana could trust and ever talk about his real sexuality and feelings towards Tzuyu, as well as his true self. They both held deep and platonic affection for each other.
Son Chaeyoung
• Last but not the least, Dahyun's best friend slash sibling-figure. An aspiring artist who's always underestimated and made fun of because of his height. Close friends with his hyung, Jeongyeon, as well. A loyal gentleman to Mina and often rages by how Sana continuously flirts with his girl, although there's no malice between the two.
