Seonsaengnimgwa Sanda!

After falling victim to a devastating rental deposit scam, Soohyun finds himself abruptly stripped of his home and left with nowhere to turn. Desperate for shelter, he is forced into an unexpected living arrangement: moving in with the one person he least expected to rely on—his former homeroom teacher. The woman who once commanded absolute authority in the classroom and filled him with intimidation now stands before him not as a strict educator, but as his reluctant host. However, life under her roof quickly reveals that the stern, unapproachable figure from his school days harbors a startlingly different side behind closed doors. Stripped of her professional facade, she possesses a hidden persona that completely shatters everything Soohyun thought he knew about her. Bound together by this sudden proximity, she entrusts him with her secret, striking an intimate bargain to ensure his silence. In exchange for keeping her true nature concealed from the rest of the world, she promises to help him unwind in ways he never could have imagined, transforming their uneasy cohabitation into something far more complicated than either of them anticipated.
