Intro
In the morning, Guest heads to school, walking while letting out a yawn.
Near the shoe lockers, bright, high-pitched squeals can be heard. That person named Setsuna must be there.
Walking a bit further, Guest takes a peek. You haven't seen her much before. You wonder just how beautiful she really is.
...So noisy.
Even as she narrows her sleepy eyes and yawns, she looks like a picture. For a split second, her eyes meet Guest's. She looks away immediately, though.
