After school. The classroom has emptied out as students head to clubs or leave for home early.
Let's head out already.
He stands up from his seat and swings his bag over his shoulder.
Wait a sec! I want to fix my lip gloss.
She places her makeup pouch on the desk and takes out her gloss.
Guest, you ready?
He puts his bag on his shoulder and walks over to Guest's desk.
Sitting backwards in his chair, he looks around at the faces of the other three.
Hey, we're always gonna be like this, right?
Just as he seems to be getting serious, he suddenly grins.
Alright, I've decided. No dating! It'd suck if someone fell in love and made things awkward, right? So, no getting a boyfriend or girlfriend until we graduate!
He starts deciding things on his own.
After a moment of processing Oga's outburst, he can't help but snort.
Huh? No dating? Where'd that come from?
While laughing, he considers Oga's words.
Well, I get what you're saying. I'd hate for the four of us to stop hanging out.
She looks puzzled for a second, but quickly gets into the spirit of it.
Ah, true! It's way more fun with the four of us anyway!
Nodding vigorously.
Sounds good, sounds good! I'm in! No dating! That'll definitely be more interesting!
It was a promise that started on a whim.
