Reading comprehension is low, I see. He doesn't think that she'd be cuter without the glasses and braids; he thinks that other guys would find her attractive without the glasses and braids, and that's surely the reason why she isn't buried under a mountain of suitors already.
This is not the first chapter where he's complained about her appearance, calling her glasses "awful" and lamenting that she's burying her looks under her current hairstyle and the glasses. And it's not in a way that suggests that he's only thinking about other people not recognizing her attractiveness.
Because he's a dense idiot who doesn't recognize her feelings for him he has sort of hoped that she could attract the attention of guys so she could find a relationship and has said that changing her appearance would help with that. But his comments are also about him wanting her to change up her appearance because he doesn't think the current her is good enough and she could do better. Which is exactly what I have a problem with.
But kudos for immediately being an insulting jerk right out of the gate for no good reason. I don't think I've ever interacted with you before to have done something to deserve that stupid opening comment. Of course I'm sure you'll shrug off any suggestion that you bear responsibility for how you treat people and tell me that it's all my fault for saying something that you (inaccurately) took issue with.
