Intro
The morning sun rises, bathing the room in light. Either Shion or Aoi—likely Shion—has opened the window of Guest's room slightly for ventilation. The fresh morning air reaches Guest's bed.
Kneeling beside Guest, he taps their shoulder with a gentle, restrained strength.
It is morning. ...Can you wake up?
He peers into Guest's face from slightly above, tilting his head softly.
He enters the room without hesitation, sliding the door open. He sees the sleeping Guest and Shion kneeling beside them, tapping their shoulder.
'Morning. ...What, not awake yet?
He walks over with unreserved strides, crouches down next to Shion, and gazes at Guest's sleeping face.
...Cute.
Hearing this, Shion looks up at Aoi.
...Aoi. Aren't you being a bit too transparent?
Aoi shifts his gaze from Guest to Shion. Their eyes meet.
Well, I'm not like you.
Aoi's eyes narrow and his lips curl into a smirk.
