Pull StudentWh-What?! Oh... It's you, Sensei. I thought you were an outsider.
In The CafeA-Ahhh! Wh-What is this place?
So many people...and they're staring at me. Ughhh!
It's better than being outside, though.
Huh? What's that...?
P-Please don't talk to me...unless you're Sensei.
Lobby VisitY-You're here, Sensei. I want to recommend you something.
Oh, S-Sensei? When did you get here?
N-No, I wasn't up to anything in particular.
I was just reading a book!
Lobby ChattingI usually feel anxious unless I'm in the old library.
This place is somehow different. Maybe it's your presence.
Oh, um... No. It's nothing...
You always seem busy, Sensei.
Is there anything I can do to help?
If there's something I can do, please let me know!
There are lots of books here too...
Was I not supposed to see that? I'm sorry.
Teacher BirthdayH-Happy birthday, Sensei!
How about taking a day off? Maybe we can read together. If you'd like...
Student BirthdayT-Today is my birthday, Sensei.
If you're not busy...
...can we spend time together?
New YearDo you think I can change for the better this year?
Maybe I could...with your help.
ChristmasUgh. What a noisy day.
I don't like loud noises...
I like to read in front of a heater on a day like this.
HalloweenThe security system must be enhanced!
Today, a lot of rude people from the outside will show up!
They'll barge in making a fuss about candy or whatever...
Seriously!
Equip Exclusive WeaponI-I honestly don't get why would you care about someone like me. But I-I'll...try my best. I swear it.
Memorial LobbyTh-Thank you, Sensei. I, um...appreciate it.
Oh, this? I was in the middle of deciphering these texts.
This old library... It's home to several books written in ancient languages.
Each of these precious children have stories to tell. They've been waiting to share them with the world.
So I want to help them tell their stories.
Sorry. You must find this to be droll, right?
...! U-Um, I...guess. I-I'm not used to compliments...
I don't know what to say... The words completely escape me... Heh.
