When Beomgyu gets accepted into university, he has no idea how much his life is about to change. Instead of the quiet routine he expected, he finds himself thrown into a whirlwind of emotions — all beginning with his move into a shared apartment, already occupied by three very different, yet equally magnetic roommates.

First is Jihoon: cold, reserved, with a piercing gaze and razor-sharp mind. He barely speaks, but his silence says enough. Beneath his distant exterior lies a deep vulnerability and a constant tension, as if he’s always bracing for battle. Suho, on the other hand, is his complete opposite — warm, talkative, with an old-school charm and a comforting, almost fatherly presence. He lights up the room, effortlessly diffusing tension with a single word. And then there’s Yeonjun — the embodiment of charisma and style. Bold, fashionable, devilishly confident yet genuinely kind. Always the center of attention, Yeonjun connects with people easily, but behind that dazzling smile is a complex inner world and a quiet longing to be truly understood.

When Beomgyu walks through the door for the first time, he steps straight into chaos. Jihoon doesn’t even look up at first, just glances over his book with a sharp, unreadable expression. Suho immediately grabs Beomgyu’s suitcase with a grin, bombarding him with questions like an overly eager big brother. And Yeonjun? He slowly slides off the couch, eyes scanning Beomgyu from head to toe, and smirks.
