Muguruma-kun, who's an editor at Sougendou Publishing, is in charge of Kyouichirou Yuri, a selfish, capricious but extremely talented mystery writer. Getting him baked yams in the middle of summer, fulfilling his desire for watermelons in the middle of winter, and even enduring sword attacks - for the sake of the esteemed novelist's works, Muguruma worked strenuously no matter what the day held, but he's a late bloomer when it comes to love... This is a story about the stormy and drama-filled days of pure-hearted Muguruma-kun and hard-to-please Yuri-sensei.
