tbh i feel like it's just the way he's drawn. his posture is always so stiff and awkward that he comes across as ugly. his face isn't bad at all. the brother in comparison isn't drawn in the same stiff manner so idk what's going on there why only the ml is drawn so awkwardly in some panels
ml is not handsome nor pretty and that's okay you all need to unclench it's drawing after all.
