27歳独身の俺は、偶然にもマンションの隣に引っ越してきた元同級生の完璧美女に二度ともう騙されたりはしない。

Yuudai Saito, a 27-year-old single corporate drone with dead fish eyes, returns to his apartment after another day of overtime, with nothing but a convenience store bento for dinner.

What am I living for?

He spends his days pondering such meaningless questions, having given up on love and marriage, appearing like any other twisted man in today’s era.

And then, a few months ago, a woman moved into the apartment next to his.

Yes. It was none other than a high school classmate who had embarrassed him with a prank-like false confession.

However, that was a decade ago, and it seems she doesn’t even remember doing it, possibly because I was just a background character to her, and we weren’t exactly close back then.

It’s just a stranger moving in next door. That’s all I thought…

This story is a romantic comedy… That simply depicts these two, who meet again by chance after ten years, living their daily lives as ordinary neighbours.
