Aru Hi, Otoko Shujinkou ga Ochitekita

“My name is Leandros Julian Terrion Etoshina.”

I’m just an ordinary college student, and he’s a man who suddenly appeared from another world. I thought our lives would never truly intersect… so how did we end up falling in love in just a few days?

“When you feel like crying, then cry as much as you want. I’ll hold you the whole time.”

“There’s no way I could ever forget you, my lady.”

But only a few days later, he disappears just as abruptly as the day he first arrived—returning to where he truly belongs, inside the pages of a 1,000‑page romance novel.

“You’re still as pure as ever, I see.”
