What Happened To Mirae

Kwon Yeon-woo is a thirty year old low-level civil servant who works in a district office; quite innocent for his age, he has been on numerous blind dates in an unsuccessful bid to find a wife. After moving into a new place, he begins to encounter a high school girl, Soo-yeong, on his way to work every morning, and she begins to develop feelings for him. Meanwhile, Kang Sook has just started working at the district office straight out of high school, and falls head over heels for older woman Kwon Ha-kyeong.

Indie musician Dong-hoon and cartoonist Jae-hee broke up a year ago. The former couple meet again after the death of the cat they owned together, and go on a night's trip to hold a funeral for their pet.

After the unusual attack on a school 'flower boy', Sung-min, on February 14, the same attacks begin to happen at different high schools on every month of the same day. Rumors say that the next victims will be at Neulparan High School.
