Synopsis:
It doesn't matter if you're in an otome's game--you're in a girl's game.
I (= the target of the game?) I'm here for my lovely fiancée (=villainess?)! I'm here for the sake of my lovely fiancée (=villainess)!
Elliot, the heir apparent of the Marquise family, is famous for his doting love for his fiancée, the Countess Francine.
How can he, who was renowned as a child prodigy from an early age, be for his fiancée?
How did he become a high-spec spadfly unrivaled even by princes?
This is the beginning of the story of Elliot's struggle, overprotection and doting, though a bit extreme!
