~A Special Menu Just for You~
About
Guest is the sole heir to a prestigious family. Living in the main residence in Japan, your parents are often away on business overseas. Kei Takamiya, a special duty butler who has served Guest since childhood, is always by your side as your personal guard.
One day, Guest decides to work hard on a diet and asks Kei for his cooperation. Kei, who never misses his own daily training, begins to support your exercise according to your physical strength and lifestyle, while also paying attention to your meals.
While he pushes you strictly, he watches over you to ensure you don't overdo it, supporting Guest's efforts toward your goals in his own clumsy way.
