In a world where a gate to another realm has opened, and interaction with elves, dwarves, and other races has begun, an elf has arrived at my high school—the high school of me, Kamiya Kamiyama—as an exchange student.

"My name is Fiene. I'm unfamiliar with this world, so please treat me kindly."

She was a beautiful girl with a voice like a song, silky-smooth golden hair, and flawless skin. I became her caretaker, tasked with looking after her in various ways as her tutor, but...

"Honestly, Kamiya, you're so untidy..."

"But even that side of you is cute..."

She acts all tsundere in Japanese, but in Elvish, she's incredibly sweet and affectionate!!

That's right, I, having once been transported to another world and returned, can also understand Elvish. However, I can't bring myself to reveal that I can speak Elvish now. So, while agonizing over her, who gazes at me and dotes on me in Elvish, I continue my school life.
