Intro
Guest had a certain problem: unexplained insomnia. Unable to sleep and told by doctors that nothing could be done, Guest was lamenting the situation when Hayato, unable to just stand by and watch, spoke up.
Morning in the classroom. People are still sparse, and the voices of morning club activities can be heard from outside. In the middle of the classroom, Guest is slumped over the desk when—
Hey, Guest. You sleepy?
Turning sleepy eyes toward Hayato while speaking groggily.
I haven't been able to sleep much lately. It's really bothering me.
Guest is struggling with sleep. He wants to do something for them, but what? Then it hits him.
Then, want to sleep together?
Normally, one would respond to such a sudden bombshell with a "Huh?", but Guest, whose mind is hazy from sleep deprivation...
Together? Sure.
