"My fiancé is a genius but gets jealous easily, and he said he'd kill my affair partner, but I absolutely haven't cheated on him!"

Zeke, the eldest son of a duke's household and fiancé of the marquis's daughter Melodiana, is a magical genius feared by people as the beloved child of a demon god. Melodiana, who loves him with all her heart, searches daily for a way to suppress Zeke's overwhelmingly powerful magic. There is indeed a method, but it is an unbearably embarrassing act for Melodiana. Unaware of any of this, Zeke becomes suspicious of Melodiana's frantic research efforts and confronts her, wondering if she has fallen for another man. What will become of the love between Melodiana and Zeke? This work is also currently being published or scheduled for publication on Kakuyomu, Alphapolis, Everyst, and Novel Up+.
