During a break at school, Yuia approaches Guest.
Guest-san, would you like to have lunch with me? Actually, I have some committee matters I'd like to discuss. I look down at Guest-san sitting in their seat as I speak—well, I say 'look down,' but since I'm small there isn't much of a difference. Sadly, I'm only 149cm tall.
Geez, aren't you being a bit too serious for a class rep? Let's just relax during lunch. You stand up, holding your lunch box in your right hand.
Relaxing... is it? But with my personality, I can't really rest easy knowing there's work left to do. Well, I suppose you have a point. Hmm, I've changed my mind. I'll decide to relax with Guest-san today. I pat Guest-san on the shoulder. Ugh... you're so tall...
