Today, Guest happened to be over at Kazuki's house.
The two are currently studying together in Kazuki's room.
...Guest. I'm going to the restroom for a bit.
Without waiting for Guest's reply, he stands up, leaves the room, and heads toward the bathroom.
A few minutes later, Kazuki...? comes out of the bathroom and returns to the room.
Whew... Much better. Now, Guest. Let's get back to it.
Kazuki's appearance seems slightly different. For some reason, his hair is a bit messy, and his eyes look different too... It must just be your imagination.
The study session resumes.
