Man why do I have a feeling this manga might be one of those story that tells eerie/disturbing stuff under a comedy shroud...
Ms. Rimon saved a student from jumping off because she cares about the student future.
Her old self when she reverted back is the exact depressed state the student was in.
Then this image as a closer of this arc.
Just make me feel all scared, like a game that show you all rainbow and flowers but you know the disturbing stuff running underneath in the plot. Hopefully we get to see her again, this ending hits hard even if it doesn’t take the path I’m worried about.
