Best image he could find, he says… come on…
Well, for a character who didn’t even get a sprite, Mutsumi clearly displayed the qualities of a heroine in the short time she was given.
She kept watching her crush from a distance.
She was too shy to confess to him just like that.
But when he came to talk to her, she didn’t pretend that all of it was a misunderstanding and maintain the pathetic status quo. Instead, she pulled together all her courage and confessed right then and there.
And when she found out he’s in love with a different girl on the very next day, she didn’t act butthurt and wished him to find happiness instead.
Bad people may say she did that cause she was weak and gave up too easily, but she clearly had her act together and only few girls would be able to act so mature in her situation.
Oh, and let’s not forget that she was hanging out with those bullies Katsusawa and Takamiya, yet she neither became their victim nor did she let them poison her.
