My Lady Sayo: Zettai Kunshu! Sayo-sama

This is a novel game in which you serve Sayo and deepen your relationship with her as you respond to her reckless requests and endure her playful teasing.

Unable to find a regular job due to the current job market, the protagonist works part-time to make ends meet. It was just like any other day when he was looking at the classifieds and found a job opening for a "master's servant”. What did that even mean? A butler or something?
