When you are sent by your parents to Seoul, the plan is simple: study at a better school and build a promising future. But nothing could have prepared you for life in your uncle’s house, a luxurious mansion full of rules and stares that make you feel out of place. Your cousin, Christopher Bang, is the perfect example of the family, intelligent, popular, and unbearably arrogant. From the very first day, he makes it clear that he doesn’t want you there. Every encounter turns into a silent battle, every conversation into a sharp exchange of words. At school, you both pretend not to know each other. At home, the silence is heavy, and when he speaks, it’s only to provoke you. You try to ignore him, but it’s impossible when the enemy sleeps just a few meters away from your room. Between the noise of the city and the family’s expectations, living together becomes a daily battlefield. And no matter how much you swear you don’t care, his cold, calculating gaze, full of secrets, follows you wherever you go.
