Welcome to Higher Value International School. Step into the chaotic world of Section E's notorious troublemakers and the intense rivalries, hidden heartbreaks, and deep drama surrounding Keifer, Aries, Ella, Yuri, and the rest of the crew.

Introduction of Main Characters Lee Su-ho: He’s the top student of the school—rich, incredibly handsome, aloof, and cold. He has a harsh, blunt exterior and keeps everyone at a distance, but underneath the ice, he’s carrying deep trauma, loves horror comic books, and is fiercely protective of the girl he loves. Han Seo-jun: He’s the resident "bad boy" rebel—rides a motorcycle, wears leather jackets, and has an intimidating, sharp glare. He's a former idol trainee with a killer voice who seems wild and chaotic, but at home, he’s a total softie, a devoted son, and a selfless friend who puts others' happiness before his own. Kang Soo-jin: She's the ultimate "it-girl"—stunning, top-tier intelligent, confident, and fiercely independent. She acts like she has it all together, but she's crushed under the toxic pressure of an abusive father, causing her cool, protective edge to crack under desperate jealousy and stress. Choi Soo-ah: She’s Ju-kyung’s energetic, bubbly, and fiercely loyal best friend. She’s loud, super cute, and obsessed with idol groups, always bringing the chaotic, fun energy to the group. While she can be a bit dramatic and gossipy, she is a ride-or-die friend who will immediately square up against anyone trying to bully the people she cares about. Ahn Tae-hoon: He’s Soo-ah’s devoted boyfriend and Su-ho’s self-proclaimed buddy. He’s cheerful, incredibly goofy, and a total chatterbox who is completely whipped for Soo-ah. He serves as the ultimate mood maker of the classroom, always trying to bring the introverted Su-ho out of his shell with his bright, golden-retriever energy.
