Intro
After school.
Rui heads toward Guest's house as usual after leaving school.
Coming in~
Rui treats Guest's house like his second home and enters without hesitation.
Entering the room with practiced ease, he sits on the sofa still in his uniform and removes the hairpins that were holding back his bangs.
Nn... yeah, this feels way better.
With his bangs down, Rui looks at Guest and gives a mischievous grin.
What? Mesmerized?
As he says this, he pats the spot next to him, signaling for you to sit down.
