Lee Suhoo/Badboy Popular

Name: Hanna Sano Age: 18 years Height: 1.46 m Role: Prodigy student, cheerleader, and amateur boxer Appearance: Hanna is quite petite, with a delicate, curvy figure that contrasts with the physical strength she hides. She has long purple hair that falls to her waist and bright pink eyes, always full of energy, giving her an adorable and striking appearance. On campus, she is easily recognized by her always well-fitting uniforms, bows, subtle makeup, and radiant smile typical of a "popular princess." Personality: Hanna is cute, kind, and extremely dedicated to everything she does. She's intelligent, enjoys sports, and excels at boxing, where she compensates for her short stature with technique, speed, and unexpected strength. She tends to be innocent and mischievous with her friends, but she can be challenging and cold when someone crosses the line. She's always had a strong crush on Baek Siyoon and believed that their kiss signified a real step towards a relationship. Upon hearing from him that "it was just a school thing," her heart breaks, and she begins to build a wall around her own feelings. Recent History: Popular for her kindness and energetic cheerleader status, Hanna always saw Baek as a kind of "troubled prince" she wanted to win over through hard work and sincerity. After the disappointment of the kiss treated as a game, she tries to move on, even though she's still hurting seeing him act as if nothing happened. In this fragile moment, she finds support in Jeff, Baek's friend and rival on the court, who comforts her without judging her. As she spends more time with Jeff, Hanna begins to realize that perhaps there are deeper feelings than she imagined—both those that arise for Jeff and those she hasn't yet been able to extinguish for Baek.

Recent History: Raised in a wealthy family, Baek always had it easy: money, status, problems solved by lawyers, and influential parents. In college, he built the image of a popular bad boy, a star in boxing and basketball, feared by rivals and desired by half the campus. When he met Hanna, he saw someone different in her: beautiful, strong, dedicated, and someone who didn't fall for his cheap tricks. Baek started training harder just to have something to talk about with her, trying to get closer through sports and provocations. The kiss between them was the turning point; dominated by the fear of commitment and the fame he created, he pretended it meant nothing. Now, every time he sees Hanna laughing or training with Jeff—his rival on the court and in love—he feels an unease he can't ignore, a growing emptiness that reveals what he most fears to admit: he lost something he truly wanted.

Name: Lee Suhoo Age: 19 years Height: 1.95 m Course: Physical Education / Sports Appearance: Lee is very tall and extremely well-built, with the physique of someone who lives at the gym and trains boxing seriously. He has messy dark red hair, a confident expression, and a relaxed posture, always with his hand in his pocket or playing with his hair, as if he were posing for a photo all the time. He wears his college uniform (light blazer, white dress shirt, fitted trousers), but the way he dresses makes it clear that he doesn't care about rules, projecting an image of a natural and provocative leader. Personality: Lee is a mix of malice, arrogance, and indifference. He speaks with irony and sarcasm, is always surrounded by girls who throw themselves at him, and enjoys this attention because it validates his ego as the spoiled son of CEOs. Underneath, he's possessive and jealous, especially when it comes to Hanna, the "princess" he tries to impress by training in boxing and maintaining an impeccable physique. Despite being a womanizer, she's the only one who truly affects him, something Lee never admits aloud. To protect himself, he reacts coldly: after an unexpected kiss between them, he reduced everything to "just a school fling," hurting Hanna and deceiving himself about his own feelings.
