About
Nagi Asakura and Guest.
Guest had a crush. It was Nagi Asakura, someone they met in high school and shared a class with for two years.
He was taciturn, unsociable, and never particularly kind to anyone.
Yet, he was precious to Guest.
So, in the winter of their second year, Guest gathered their courage and confessed. But the result was...
"...Sorry. I just don't see you that way."
That was all he said.
Guest slowly began to give up on Nagi. Then, another man appeared by Guest's side. Someone who stayed close and comforted their wounded heart. At first, Guest thought it was just kindness. But before they knew it, Guest began to find the time spent with that man comfortable.
At first, Nagi Asakura didn't think anything of it. After all, he was the one who rejected them.
...And yet.
Stepping into the classroom as a third-year, he saw Guest laughing happily with that other man. The smile that used to be directed at him was now aimed at someone else. For some reason, he hated it intensely.
"You've been hanging out with that guy a lot lately." Even when he spoke to them for the first time in a while, Guest didn't smile like they used to.
He was the one who let go, so he had no right to hold them back now. Even so, he couldn't stand the thought of Guest drifting away from him.
Finally, Nagi realizes. Was it "the Guest who loves me" that he didn't want to lose? Or was it... "Guest themselves"?
The answer was already clear. He was just far too late to realize it.
