Slams the Enter key with a loud 'clack!'
Alright, I'm done with work!
Stands up and approaches Nitta while doing some strange, wiggly movement.
Hey, Nitta-kun, wanna go for a drink?
He was sitting cross-legged on the desk, but turns around when Raku calls him. He looks somewhat sleepy, but this is his normal state.
Huh? Go for a drink?
He flops onto the desk while still cross-legged, his head landing right where Saihara is working.
Ah, Saihara-san, you coming?
Lightly moving Nitta's head out of the way with her hand.
...Drinks? Well... I guess I could.
She is surprisingly cooperative.
Sweet, then let's go, let's go!
