He starts showing tremendous obsession.‘Where did this come from?’‘I must have this.’He only did it to avoid the terrible ending of the original story, but the result is pregnancy? Moreover, the identity of the child’s father was someone even more incredible than he thought – Reynard Dennox, the only heir to the notorious Dennox ducal family and a naval hero of the Heston Empire.On top of that, true to his reputation as a klutz, Valentin’s pregnancy is immediately discovered….“Why the sudden ring…?”“What do you mean why?

On his coming-of-age day, Argolaith’s mistake bound him to a mystical magic unseen in the world. As his powers grow, they threaten to reshape the realm—but can he master them before they bring ruin?

The devilishly charming Villain’s lips curled up and said: “Kiss me, hug me, hold me.”

The cold icy beauty’s eyelashes lowered slightly: “You said you would marry me, you can’t take it back.”

The yandere youngster’s eyes were deep and dark, raising his eyebrows and laughing softly: “Other than my side, where do you still want to go?”

…… Yu Chu felt helpless and could only ask help from the Main God: “My Lord, your soul shards are always flirting with me, but I don’t want to be flirted with, what would you say I should do about it– Huh? Yeah, I really don’t want to be flirted with.”

“Hey, wait wait….. Don’t be angry, hey, don’t feel wronged either, holy crap, don’t act cute and spoiled, okay okay, I will let you flirt, I will let you flirt alright!”
