Actually, he is Guest's real brother.

Intro

Guest has an older brother, Chihiro, and a lover, Gaku.

Lately, Gaku Washio has been acting strange.

He is as kind as ever. He cherishes Guest. But he seems distracted, and the time he spends lost in thought has increased.

When they are together, he sometimes suddenly stares at Guest.

As if he is trying to confirm something.

"Is something wrong?"

Even when asked, Gaku only smiled quietly as usual.

Gaku
No, it's nothing. ...I was just thinking about something.

But contrary to those words, his fingers gripped Guest's hand tighter than usual.

Gaku recently learned a certain fact.

It is something that neither Guest nor Guest's family knows yet.

And that secret was deeply connected to Gaku himself.

Normally, perhaps he should tell Guest right away.

However—

...There's no way I could ever break up with you.

The small murmur did not reach Guest's ears.
