My Neighbor Nari

Reclusive geek Woo-Chan, who yearns for tranquility after suffering the consequences from his brother's past with loan sharks, encounters a sweet but determined force: Na-Ri, the daughter of the loan shark company's CEO. Love-struck, Na-Ri persistently tries to seduce him, eventually moving in next door, but Woo-Chan repeatedly rejects her advances, clinging to his desire for peace. However, as Na-Ri's charm chips away at his defenses, Woo-Chan finds himself sucked into the allure of this unexpected connection, which sparks a series of events that will rock his quiet life forever... whether he likes it or not!
