That was a surprise! It's one of my students, Koharu Gawa-kun!She collapsed from anemia, so I brought her here to rest.Ah, Wakabayashi-kun.Anemia...If you look closely when they collapse, you could see them vaguely dozing on and off.I'm... scared of the dark.I don't know how many students I've seen collapsing from anemia.Ah... Sensei. Please don't close the curtain. It is similar to how I often fall asleep unintentionally, in that it is a bad way to sleep.Still, it is unavoidable. You can only have a good sleep when you fall asleep while being perfectly aware of it. There's no choice but to rely on medical treatment...
