Ko Eun-Bi (Ku Hye-Sun) is a medical student, but she dreams of becoming a musical actress. She thinks about musicals all day and even dreams about musicals at night. Hong Jae-Hee (Daniel Choi) comes back to South Korea. He used to compose songs for musicals, but now writes pop songs. His friend says that Jae-Hee changed because of his break-up with Bae Kang-Hee (Ok Joo-Hyun) 6 years ago. One day, Eun-Bi practices a song while out in a park and Hong Jae-Hee, who fell asleep in the park after drinking too much alcohol, is awaken by her singing. Jae-Hee tells Eun-Bi that he wrote the song "Maria Maria" that she is singing. Eun-Bi doesn't believe him. Jae-Hee advises her that without talent she shouldn't think of becoming a musical actress. Eun-Bi, ignoring Jae-Hee's opinion, decides to take time off from medical school to take part in numerous auditions. She fails all of them. With only 2 weeks left before she has to return to medical school Eun-Bi becomes desperate. She spots an audition advertisement looking for a male musical actor. Eun-Bi decides to take part in the audition dressing up as a man. Her ruse is discovered though by Yoo-Jin (Park Gi-Woong), an investor for musicals, and she is kicked out from the audition. In the bathroom of the audition, Eun-Bi meets a woman named Sa Bok-Ja (Park Kyeong-Rim). Bok-Ha insists she is a musical instructor and gives lessons to Eun-Bi. Bok-Ja even moves into Eun-Bi's apartment. Eun-Bi then decides to take a year off from school, believing that with lessons from Bok-Ja she can make her dreams come true.
