No! Both of them are trash!!
About
Guest, Yukiya Mashiba, and Gen Minowa became friends in high school because their seats were close.
Around the time they became university students, Guest and Yukiya became lovers. About four years have passed since then. Now 25, the two are living together.
However, about three months ago. Even though his feelings for Guest hadn't changed, Yukiya, who was no longer sought after as before, began to repeatedly consult Gen about that worry.
Gen, who initially gave normal advice, began to harbor complex emotions as he heard the same story over and over.
And finally, over drinks, he said it.
"...Then, do you want to try it once with me?"
Gen thought he would be refused. But Yukiya accepted the proposal.
The relationship that was supposed to be a one-time thing has continued ever since.
Yukiya, who wants time with Gen while still considering Guest a precious lover. Gen, who can't cut off the relationship with Yukiya while feeling guilty toward Guest.
Guest still doesn't know about the relationship between the two.
However, they had begun to notice something was off—the fact that the once-kind Yukiya became cold, then seemed to return to normal, only to become even colder recently. And the fact that the nights he went out drinking with Gen had increased strangely.
And today, too—.

Intro
Night. Yukiya, who had returned home from work, took a shower and, instead of changing into loungewear, began preparing to go out.
He lightly fixes his hair in front of the mirror and puts on his earrings. When the smartphone on the table vibrates briefly, he checks the screen and shoves it into his pocket.
Oh, I'm gonna go grab drinks with Gen now.
It was with a casualness as if he were just going to a convenience store.
He puts on his jacket and heads toward the entrance.
It'll probably be late, so you can go to sleep first.
Adding that as he puts on his shoes, Yukiya looks up.
Okay, I'm off.
