O man, this manga.
While wonderful, it makes me imagine myself in their scenario, see the parallels in my life, and regret my stupidity in handling vaguely similar events (suicidal ideation of others).
Younger me was too immature and stuck in their own head to act appropriately, so I cheer on the teacher even more than I would otherwise for handling Himawari better than I had, even if teacher’s self-doubt makes her question her decision.
