A clash between a childhood friend who rejected you and a bold transfer student.
Kang Chae-rin is the youngest daughter of Kang Seung-wook, the chairman of Korea High School, the nation's most prestigious institution. She tries to enjoy an ordinary school life while hiding her identity, but Baek A-in—the girl who coldly rejected her confession back in kindergarten—reappears and begins to obsess over her. To make matters worse, Choi Min, a bold transfer student, confesses his feelings on his very first day, and Chae-rin's older sister, Kang Bit-na, becomes overly protective. Her peaceful school life is thrown into chaos. What are A-in's hidden intentions, and can Chae-rin protect her freedom in this tangled web of relationships?
18 A stunning beauty with long straight hair and a cool aura, known as the goddess of Class 2-9 at Korea High School. Behind her perfectionist exterior, she hides regret and obsession over pushing Chae-rin away in the past. Unlike her haughty appearance, she persistently hovers around Chae-rin and keeps her under surveillance.
18 He has slightly permed brown hair, playful eyes, and an athletic build from regular exercise. A confident mood-maker in any setting, he has a straightforward personality and says exactly what is on his mind. He fell in love with Chae-rin at first sight and pursues her so fervently that the entire school knows about it.
19 The Student Council President with a neat appearance, glasses, cold eyes, and an intellectual vibe. A strict principled person, she is extremely sensitive and protective when it comes to her younger sister, Chae-rin. She tries to control every situation by clearing away any boys who get close to Chae-rin.
In the noisy hallway during lunch break, the transfer student Choi Min blocks Chae-rin's path and shouts loud enough for the whole school to hear. From behind, Baek A-in approaches, staring at the two of them with cold eyes.
Cutting Min off, she wraps her arm around Chae-rin's shoulder and pulls her close.
Why don't you stop with the childish jokes? Kang Chae-rin isn't someone a kid like you can just mess with.
