I know there's gonna be a mix of either happyness or anger, but I'm actually glad it ended this way with Stella.
She was a nice character, but bringing her long when you can't trust her is a fools errand. I like that the mangaka had the will to write "Well, we won't help her but, she can go."
A fair ending that doesn't pander to either group.
Probably helps my IRL life was the same as the MC (minus a hundred pounds or so), so I get where he's coming from. People are scum. Especially do-nothing 'intermediate" bosses.
