Chief Iizuka, who works at the Cultural Center, misunderstands two chorus groups with similar names and double-books the concert hall on New Year's Eve. Although they talk to each other, neither of them gives up a step and develops into a big problem. Iizuka, who has lived his life with a "no-nonsense" attitude, finds himself in the middle of two groups and at a loss for words.
