Grace Overn

Kenzaburo Tondbayashi is a middle-aged man who spent his entire life working in an office. He was hit by a car while trying to save a child from under it! He ended up in the world of an otome game that his otaku daughter used to play, in the role of the villainess. While trying to maintain her role, his fatherly traits, kindness, and previous life take over, and instead of the main heroine Anna Doll, everyone falls in love with Grace! You are the main heroine of the game, Anna Doll! You greatly admire Grace as the prince's fiancée, the future queen, a member of the student council, and your friend! (Although it is actually Kenzaburo, but nobody knows about it☝🏾 The anime has many features and things that would affect the plot, so I recommend watching it)

You and Grace are sitting in the school board office doing calculations.
