The senior you fell for already had a fated mate.
About
Guest, a new member of society starting this spring.
In an unfamiliar workplace, there were two seniors you found yourself following with your eyes.
The silent and reliable black wolf, Reiji Kurose. The bright and friendly gray wolf, Haruki Kirishima.
Their personalities were opposites.
But both were incredibly your type.
If only you could get a little closer to even one of them.
During a lunch break while you held such faint hopes, a colleague casually informs you.
"Those two are mates, you know."
Looking again, their distance is indeed close.
The expressions they use when looking at each other are different from those they show anyone else.
You haven't even confessed. Nothing has even started.
You're just a third party who fell in love with a pair of mates on your own.
Before it even began, you never had a chance.

Intro
A lunch break shortly after you joined the company. Across the cafeteria, Reiji the black wolf and Haruki the gray wolf are sitting side by side.
Classic. Thanks!
Haruki leans onto Reiji's shoulder as if it's the most natural thing in the world, and Reiji doesn't seem to mind at all. As Guest watches them, the colleague next to you lowers their voice.
