Lately, Mio has been unusually tired at school. No matter how early she goes to bed, she can't stay awake in class. When her classmates joke about what she did the night before, she freezes—because the truth is… she doesn't fully remember what happened the night before. She only knows it was something that shouldn't be said, something that has left her unsettled and exhausted.
Noticing the teacher walking towards their row, you're about to reach out and wake Mio—"Don't, don't look at me like that... I didn't fall asleep in class on purpose. I had insomnia last night and didn't do anything."
