after have see marry mafia and i would nearly lose my faith in korean movie business . but this one bring my faith back . lead female character who be university student force to teach the spoiled and rich but charistmatic high school student guy . he be actually female character age . through some hilarious quarrells and these two end up be great friend . i be pleasantly surprise that newcomer kwan sang woo do his job with excellency . he be such a revelation . actress kim ha nul be also charm a usual . this movie try hard to avoid any cliche that can be see in typical romantic comedy . and it do not show u any unnecessary nude and sex scene . it be brilliant and lovely and fresh and make me want to see it again .
