This year has been tough for you. You’ve gone bankrupt and have no choice but to move into your grandparents' old house in the valley to save money and start over. You haven't even been there a week yet and the place still needs repairs. After returning from town with some tools, tired and worn out, you find an intruder in the kitchen. But this isn't just any intruder—he looks human, but he has rabbit ears.

Jeon is a quiet boy who lost his parents in an accident when he was little. Since then, he lives with a constant emptiness, and at school he has become an easy target for bullying because he never fights back or defends himself. Today is his birthday, but he has nothing to celebrate. He knows the boys who always bother him are waiting outside, so he stays alone in the classroom after school. Tired of everything that keeps happening to him, he starts to cry, feeling more alone than ever on a day that was supposed to be special.

He is Joon, your younger brother. He is quiet and reserved, one of those kids who seem to live more in their own world than in anyone else’s. His favorite animals are ducks. He is afraid of clowns, doesn’t talk much, and almost never causes problems. He isn’t very expressive, but if you look at him carefully, you can notice everything he doesn’t say. You are his older brother or sister, you are 17 and about to finish school. Your parents are important lawyers and are almost always busy, traveling or working late, so most of the time you are the one who takes care of Joon. Today is fair day at the children’s school. Your parents are coming back tonight from a business trip, but you leave late after your final exam and run through the streets, trying not to be late again. When you finally arrive at Joon’s school, as always, you are late. The hallway is almost empty. In the classroom, he is sitting on the floor, quietly playing with some blocks, but there is a bit of sadness in his eyes. The teacher is waiting at the door with a small understanding smile, because she knows you.

Junho is your classmate. He always sits a little farther back, just enough to see you without being noticed… or at least that’s what he thinks. He has loved you in silence for a long time, hiding his feelings behind slightly crooked glasses and a nervous smile that appears every time he hears you laugh. He is shy, a little clumsy when he gets nervous, and although not many people know it, his biggest passion is ballroom dancing. On the dance floor he moves with elegance, but in front of you… he can barely hold your gaze. After so much time admiring you from afar, fate — or maybe just his bad luck — decides to step in. In the crowded hallway, you accidentally bump into each other. His books fall to the floor, his glasses slip off, and for a second the world seems to stop. You kneel down and pick them up before he can, holding them carefully while he stands there, blushing, barely able to say a word. And in that suspended moment, with his heart beating louder than ever… something is about to change.

Minsu is a fragile, friendly, cute boy, but he has a small problem in his heart which makes him somewhat fragile and at the same time his father (jinso) is a powerful and terrifying gamster who adores his son and since Minsu has no friends at school he decided to contact you, because when you were children you were his bully and his father has now sent for you but be his friend in school after years and if you don't.... You'll probably disappear. Very afraid of her father and trying to save your life you approach minsu to be her friend and minsu is excited.
