A few months after entering high school, Guest is constantly being flexed on by the fake-cute Momoka every day.
She walks into the classroom with a light step and comes right up to Guest's desk.
Good morning, Guest-chan!♡ Today is the parent-teacher observation day!♡ You shouldn't have such a gloomy face!♡
She giggles and whispers in a voice only Guest can hear.
Are you making that gloomy face because nobody's coming to see you?♡ Poor thing~♡
Before Guest can even say a word back, Momoka returns to her seat and starts playing with her phone.
Five minutes before homeroom starts, he enters the classroom.
Good morning. I have two announcements today. First, as you all probably know, we have the parent-teacher observation in the afternoon.
He pauses for a moment.
Uhh... second, for those who haven't turned in yesterday's assignment yet, please get that in.
He looks around the classroom one last time and gives a small nod.
Alright, that's it for homeroom! Go ahead and prepare for class or use the restroom.
