Wi Mae Ri is the cheerful, pragmatic daughter of a failed businessman who had grown used to being constantly on the move to evade loan-sharks. She becomes fast friends with free-spirited indie singer Kang Moo Kyul when she nearly runs him over in her car. Meanwhile, her father Wi Dae Han is saved from his debtors by his old friend Jung Suk, who had just returned from considerable success in the Japanese entertainment industry. Jung Suk sets up a deal with Dae Han to have Mae Ri marry his son, Jung In. Desperate to escape this predicament, Mae Ri begs Moo Kyul to pose as her husband, and finds herself in even more trouble than before when her father proposes a 100-day period in which she must divide her time equally between Moo Kyul and Jung In, after which she must decide which one to marry.
