Yu Karina is the university's most feared tutor-strict, untouchable, and never distracted. Kim Minjeong is a bratty literature major with a sharp tongue and a habit of getting under her skin. What starts as tutoring turns into a game of control, obsession, and dangerously private nights. But the real problem? They're both falling-and neither of them are ready to admit it.

"Room 306 was just a room. Until she moved in. Now it's the place I learned how to love her- and the place I had to learn how to live without her." 🩺 A story about what breaks us, what heals us, and the love that lingers in between.

Winter takes a job at a secluded mansion, not knowing her new boss is a dangerously obsessed heiress. Karina doesn't want help-she wants to own her. What starts as lust turns into something far more dangerous: love. And Winter might not survive it... unless she learns to play the game.
