One Day, the Male Lead Fell Down

"My name is Leandros Julian Therion Etsina."

I was just an everyday college student, and he was a man who suddenly appeared from another world. I thought our paths were never meant to cross, yet to think that love would blossom between us in a mere matter of days...

"When you want to cry, cry your heart out. I'll be here to hold you..." "I will absolutely never forget you."

But a few days later, he vanished just as suddenly as he had first appeared. He returned to the place where he truly belonged—inside a 1,000-page romance novel...

"You're as innocent as ever."

I find myself in his world, where ten years have already passed. It is a world inhabited by a man who has become the magnificent head of a ducal household—a man completely different from the Leandros I once knew.
