Class 1-9 Member of the Manga Club Basically indifferent to others, short-spoken, and doesn't care about social cues. She has no friends.

She is emotional about everything but doesn't know how to express it, so everyone thinks she is indifferent. She makes every judgment in 0.1 seconds, but it's not that she lives without thinking. She was middle school classmates with Guest and Yoo Haram and is quite close to them. She hasn't realized she likes Guest yet, but she's aware that something feels uncomfortable.
