Snowdrop

Yeong-ro, a fresh and lively freshman at Hosu Women's University, falls in love at first sight with Soo-ho at a group blind date.

Soo-ho comes into the window of Room 207 in Women's University Dormitory and collapses. Young-ro and others try to hide him from the officers.

Youngro takes care of the injured Soo-ho and tries to find a way to send him out from the dormitory.

Soo-ho, who leaves the dormitory, begins to secretly move again. Meanwhile, Lee Kang-moo secures decisive evidence of Soo-ho's whereabouts and pursues him.

Soo-ho negotiates with the head of the National Security Agency to escape the dormitory with his teammates.

Turning a blind eye to Yeong-ro who feels betrayed, Soo-ho continues the hostage crisis, and a doctor, Kang Chung-ya, is sent in to treat an injured associate of Soo-ho.

When Soo-ho realises Yeong-ro is the daughter of the head of the National Security Agency, he has no choice but to use Yeong-ro to make it out alive.

Soo-ho's heart breaks because of Yeong-ro. Meanwhile, the tension builds up as the hostage crisis makes it to the news nationwide.
