After finding out that Haruka is working to get him a Christmas present, Yūto decides to apply for a well-paying job as a part-time butler. He gets the job, but he must unfortunately serve the selfish and demanding Tōka Tennōji, a girl one year his junior, whose previous part-time butlers quit after a day or less at her command. Yūto has his work cut out for him, but soon finds that there is more to Tōka's situation than he initially realized. Through kindness and hard work he manages to gain Tōka's favor, but a certain situation results in damages that cost him nearly all of his pay.
