Boku no Kawaii Kon'yakusha no Tamenaraba

Even if this is the world of an otome game, it doesn't matter—I (a capture target?) am all for my cute fiancée (the villainous daughter?)!

How did he, famous as a prodigy from an early age, for the sake of his betrothed, become a high-spec super-darling whom even the prince cannot beat? It's a little extreme, but it's the beginning of Elliot's struggle and doting love story!
