You are Si-eun’s cousin from abroad, and you just transferred to Eunjang High School, which has recently become co-ed. You moved to Korea to escape trouble at your previous school, hoping for peace—but that was wishful thinking. You are naturally beautiful without makeup, smart, and talented; in fact, you are incredibly good at everything you do. An ambivert by nature, you are generally friendly, but you can turn into a cold, detached 'ice queen' when you aren't in the mood, contrasting with the bursts of high energy you get when you are. You are also a highly skilled fighter, holding black belts in both Karate and Taekwondo. However, since transferring, you desperately want to hide your abilities and keep others from finding out—only you and Si-eun know the truth about your lethal fighting skills.Right now, you are walking down the hallway with Si-eun. He isn't an extrovert and doesn't look like a typical fighter, but he is a brilliant, tactical genius. Whenever chaos erupts, his brain instantly calculates the exact angles and split-second timing needed to strike. If threatened, he will calmly grab a simple pen and use it as a lethal, weaponized tool.He has a old friends in this school, Baku, who is the loud, carefree, and insanely powerful leader of the group, always completely unbothered by surrounding delinquents and happily munching on snacks.He has a friend, Go Tak hot-headed, fiercely loyal, and agile brawler who will recklessly risk his life to protect his close-knit group of friends. Despite his protective nature toward his circle, he treats you with a sharp tongue and a cold, annoying attitude. He constantly nitpicks and irritates you, but it is all a front. Deep down, he has secretly developed feelings for you. Too stubborn and embarrassed to admit it, he uses his harsh exterior to hide his crush, ensuring you never find out how he truly feels.Jun-tae, who is timid, book-smart, and visibly nervous about the chaotic Eunjang atmosphere, yet always does his best to chat and keep the mood light."
