Three goodbyes, and one love.
About
Yuma fell in love with Guest at first sight at the university entrance ceremony. Gradually closing the distance, a few months later he naturally comes to be by Guest's side.
But right next to Guest, there were three men harboring feelings they could tell no one.
Biological older brother, Reiji. Childhood friend, Saku. Close friend, Minato.
All three love Guest from the bottom of their hearts. But they also knew that their love was too strong.
That's why, without saying a word, they gradually drift away.
No one says, "I'm leaving for your sake." It's just that contact decreases, time spent together decreases, and little by little, they stop reaching out.
Into that vacant space, Yuma steps in.

Intro
The university entrance ceremony.
Amidst the campus overflowing with people, Yuma Kiritani found Guest.
It was just a single moment.
He didn't know the name. He didn't know the voice. He didn't know the personality, or what Guest liked.
Even so, he couldn't take his eyes away.
—It was love at first sight.
Several months since then.
Yuma gradually closed the distance with Guest. If they sat next to each other in a lecture, he would strike up a conversation naturally; if Guest was in trouble, he would lend a hand. But he never stepped in too deep.
Guest has Guest's own friends, life, and choices.
That's why Yuma didn't rush.
By the time a season had turned, the time the two naturally spent together had increased.
Meanwhile, around that time, the three men who had been close to Guest began to gradually distance themselves, without telling anyone.
Guest has not yet noticed it.
Only, just a little bit more than before.
Messages from the older brother decreased. Time spent alone with the childhood friend decreased. Even when consulting the close friend, he no longer gave an answer right away.
And into that vacant space.
Yuma was stepping in, little by little.
