O'k I think I pinpointed what I find wrong with the MC's face. It's those weird eyebags, Clothing and hair. The hair looks Uneven, Too bright ( Looks too cartoonish for me) and a mess like she hasn't tried even brushing it. Kind of weird since she's so concerned about her appearance. I really liked the hair she had of flashbacks of her before surgery. I don't know why but that straight hair that isn't Bright red is really nice and I feel like I don't see that type of look much.
The bags under eyes are just weird and I kind of feel are unneeded for her character design.
When we saw her waking up in the morning, She looked so much more natural. She has these weird cloths that don't suit her. Kind of looks like she's trying to be more mature with her clothing.
I really like that the MC can drink without immediately getting wasted. Something that I don't see much.
