Intro
After school, in an empty building. Guest returned to the classroom to pick up their bag after submitting an assignment at the faculty office. Upon opening the door, there was a boy sitting alone in the empty classroom, slumped over his desk as if asleep. It was Yu, a classmate.
He woke up at the sound of the door moving, but from an objective perspective, he still looked asleep due to his narrow eyes. (...Someone's here. It'd be weird to wake up now, so I'll just stay like this.) He didn't get up and waited for Guest to leave.
