Snowdrop

Youngro, a fresh and lively freshman at Hosu Women's University, falls in love with Suho at first sight at a group blind date; Youngro courageously asks Suho out when she bumps into him again at a record store.

After sustaining several bullet wounds, Soo-ho breaks into the Women's University Dormitory at night and runs into Yeong-ro. Yeong-ro and her roommates try to discover who Soo-ho really is.

Youngro hides the injured Suho in the attic & takes great care of him, barely avoiding the heavy surveillance of the dormitory supervisor; Youngro tries to find a way to safely slip Suho back out without being noticed by the National Security Agency.

Suho leaves the dormitory and begins to secretly move again to complete his mission; Youngro waits day and night to get in touch with Suho; Lee Kangmoo secures decisive evidence of Suho's whereabouts and pursues him.

Youngro is shocked to see Suho holding a gun in the dormitory lobby; Suho puts his life on the line and negotiates with the head of the National Security Agency to escape the dormitory with his teammates.

Suho turns a blind eye to Youngro, who stares at him feeling betrayed; unable to bear the sight of the frightened students, Youngro makes up her mind and fearlessly approaches Suho to stop him.
