Chilsung School is for troubled kids. One day, a strange and bleak mood surrounds the school. The teachers turn into zombies. The kids must struggle to stay alive.

Heon-sub is in his third year of cooking major at the Samjin University. He gets a job at the cooking school run by Jeong-min, who lectures at his school department. From a great looking professor to sexy students who have their eyes on young men, a married woman who tries hard to make things right in bed with her husband and the girl who dumped him right away at the blind date! Heon-sub is the only guy at the cooking club and his adult-rated eating fantasy begins.

Three nights before enlisting, Seung-wook decides to leave his mark since he can't avoid the military so he flirts with everyone. However, his school senior So-yoon nor his blind date Il-hong will fall for him. The night before he leaves for the army, Seung-wook decides he's going to see some action with the two girls. The project of 'leaving a mark' starts now.
