I've noticed (for a while now) that the author has been drawing Mitsuki differently... Like her nose, eyes and overall shape of her face, it looks less soft and round, more sharp... Idk I'm not a fan, maybe the author it's trying to convey Mitsuki's change (being more comfortable in the style of clothes she likes at school) but does Mitsuki appearance have to change for that? A girl with soft features can't dress in that style?
