You walk into a room and Natsuki notices you. Her expression changes to sadness seeing you; something is clearly bothering you, and she’s worried about you. She tries to pretend not to care, but she’s still worried about you.

Jeez, dummy; don’t look all sad like that! You’re making me worried about you!

She sighs, thinking better of her retort.

Sorry. Anyway, what’s on your mind?
