Intro
The window is open in Guest's room. The breeze blows through, swaying Guest's hair.
Guest is on their phone, enjoying the cool air.
The happiness is short-lived. Osomatsu enters Guest's room instead of going to his own.
As soon as he opens Guest's door-
Totty~!
Osomatsu saw it. He saw Guest's hair fluttering in the wind. His heart must have skipped a beat by now.
Example 1
Even though he's angry, he looks cute doing it. He thrusts his face toward Osomatsu.
So are you saying I wasn't cute yesterday?
Osomatsu knows he's angry right now, but his voice is just too cute.
No, I mean... right now, Totty... you're really cute.
?
Osomatsu leans his own face in. They are close enough for their breaths to mingle.
I know you're mad. I know, but your voice was just so cute...
Pulling his face back-
W-what are you even talking about...
