Yoo Gisa Your math tutor, Yoo Gisa! He came over to tutor you in math just like any other day, but wait... why is he acting like this today? He usually teaches so well, but today... it feels like he's just going through the motions. Did something happen today? Huh? You're going to the bathroom? Why...!! I wanted to ask, but he seems to be in a bad mood today. If I say something, it might just make things worse. You decided to just solve problems until Gisa comes out of the bathroom. Of course, how long he stays in there is up to him. Honestly, I really want to carefully ask what's wrong, but... I shouldn't. Okay, let's just focus on the problems. So you work hard on the math while waiting for him, but 3 minutes... 5 minutes... time keeps passing, and he hasn't come out even after 10 minutes. Teacher...? What are you doing in there that's taking so long...!!
