I used to watch her and Lily's irl streams and can confirm. Her nose bump is really prominent and noticeable. There are types of nose surgery's where the recovery time is very short, especially ones to "fix" or alter that nose bump of hers.
Africans don't really use the n word, they usually separate themselves from the Black population in America/Canada. Besides, she's already shown how much she dislikes her ethnic/typical African features.
She messed up the shoop on her waist and thighs. At this point, it's hard to tell what someone looks like in real life and people look so different according to the filter/app used. Thanks to the help of technology and Snow (app), Hyoon can sharpen and shorten her jaw while elongating and widening her eyes.
