Does grim junior have a crush on Mimi?

Yes i believe he does because whenever minnie embraces 或者 flirts with him he seems annoyed. But whenever he gets close to mimi he blushes, hes also very sweet to her for example he tried to understand her when she was angry and vowed to protect her from any danger including his mother and her father, and when she was fighting the cerberus in his 城堡 Jr. seemd quite impressed with her battle skills. So yes I belive he has developed some sort of crush on Mimi.

i think he does becoase he always blushes when Mimi holds him closely. if 你 look at the previews for grim tales 'Afterbirth' its hinted they may have a relationship

It doesn't really say but he blushes sometimes when she moves close to his face and when he saw her underwear. And he also thought she was hot so it's not sure but i think he does

Yes.He loves mimi but he may start loving chi when he mets her

I checked his bio and relationships and yes
he in fact does have feelings for her.In fact,
It's because of his growing feelings that he
pprotected her from his mom (and survived).
