If you're a fan of Bi Rain...then you won't like to miss his BEST role ever.... It's one of writer Lee's great works "she also wrote Sorry I Love You, A Love To Kill, Thank You, Innocent Man..." The plot for this show was really great and the acting was fabulous... both Rain and Gong Hyo Jin played their roles perfectly but the big surprise was Lee Dong Gun...he was so great that you won't mind seeing him end up with Sang Doo (the male lead) instead of Eun Hwan... for short this drama has it all from humor to drama to romance to school...For me it's Just a must watch ^^
