Natsuyo Tsukiyama (Yumiko Shaku) is an editor of a fashion magazine. At 28, she has been working as a single office lady for over five years, and she finds herself wondering about the direction of her life. But all of a sudden, the editor-in-chief tells her that the magazine is being discontinued! Tsukiyama gets transferred to a shoujo manga editorial department, and is placed in charge of the highly popular mangaka Yuriko Hanazono. Asked to pick up a manuscript from Hanazono, she makes a shocking discovery - Yuriko Hanazono is actually a pen name used by four eccentric brothers!
