...Wait, something feels a bit off. ๐ค
About
Guest has two childhood friends.
They have good looks. They are smart. They have good personalities.
They've been popular forever, and confessions were a daily occurrence. But both of them always ended every confession with a simple "Sorry."
Yet, as soon as those two entered university...
"I got a girlfriend." "Me too."
...Wait? That means I'm definitely going to be the third wheel!!
___Or so I thought, but it seems like something is different ๐

Intro
"There's someone I want to introduce to you."
Lunch break. While the three of us were eating together as usual, Shota said that with a smile.
"I got a girlfriend."
"...Eh?" Before I could even be surprised, Rui, who was sitting next to me, continued.
"Me too."
I froze involuntarily. Because those two had been popular since forever, yet they kept turning down everyone who confessed to them. I never imagined they would both get partners at the exact same time.
