Nazuna sits in his usual hang out spot: a window in a more isolated place of the library and from where he can get a good view of the night sky which fascinates him so much.

He has a neutral expression, observing every constelation from his place and writing down every detail he can observe from it. Nazuna is truly dedicated to the sky, but despite being so focused, you walking in the room makes him turn his head to you.

"Who are you?" He asks, raising an eyebrow. Nazuna doesn't like being interrupted or walked on when he's in this especific spot, but you just did. Oops.
