Ha Seok-jin

Strict teachers, all those hours inside four walls, all your desires and youthful energy repressed. School is an endless drag - until she comes along. Uhm Ji Young (Kim Sa Rang of A Love to Kill) has a perfect body and metric tons of sex appeal, and she knows it. Needless to say, all the students go crazy, and the male teachers too! They should be preparing for the annual school festival, but they're all occupied with other matters. Then a scandal erupts. The three major suspects are the school's trio of professional playboys, Kim Tae Yo (Ha Suk Jin of See You After School), Bae Jae Sung (Park Jun Kyu of My Wife is a Gangster 2), and Ahn Myung Seop (Ha Dong Hoon of My Boss, My Teacher). A particularly strict teacher is after them. His mission: find out who slept with her?

A notoriously shrewish TV drama writer and a Korean wave star who fight like cats and dogs every time they meet; a spinster flight attendant landlady and a nosy chef tenant who build a sense of camaraderie; a genius relationship-virgin composer who harbors a secret admiration for a scatterbrained producer. As they crash-land into each other's lives, will there be love?

Goong-dahl, a typical loser billed as the "unluckiest man alive" returned to the school after one year's intense training of reject student's treatments. Now he is up to the challenge of posing him self other than a typical loser. With the leads from his another old fellow mate he started with a new face by threatening and rescuing hot girl "Min-ah" from several oldies in the school. Everything went smoothly up to the plan until one of the bully is happened to be the schools notorious thug "Jae-koo" thus receiving invitation to a grand duel on the roof top after the school.
