The Girl Downstairs

Lee Joon arrives at Minsong University hoping to reconnect with Kim Margo, the girl he once admired in high school. Instead, his first days are thrown off course when he’s confronted by his new downstairs neighbor, Lee Duna—a striking former idol whose impulsive, volatile behavior quickly disrupts his routine.

As Joon tries to arrange time with Margo, she repeatedly keeps her distance, leaving him uncertain about where he stands. Matters grow even more complicated after he meets fellow student Choi Ira at a party, where a daring game sparks her interest in him. With Duna’s difficult past and Margo’s strained family situation gradually coming into view, Joon is left to navigate a messy love polygon and the feelings he can no longer ignore.
