On a serious note, it’s not a good idea to justify a weight that low when women have been constantly told to be 50kg or less no matter their heights because it’s considered the “norm”. Especially in places like Korea like this manhwa is from where women are constantly told they’re fat if they’re over 50kg. It’s extremely difficult to maintain that weight and it’s EXTREMELY rare for a woman to have a weight that low unless she’s burning through shit ton of calories daily. Not to mention women’s weight fluctuates constantly unlike men’s due to their cycle. Also there is no woman on earth with a body like hers that weighs that much. Weight distribution does not work like that I assure you.
Once again… I’m not male lol I don’t understand why you guys think that… I get what you’re saying about unrealistic beauty standards, especially in places where women are pressured to stay under a certain weight. But saying “no woman on earth” can look like this at 5’4 and at 105 isn’t really accurate either. Literally look at sohee from ALICE a popular girl k-idol that weights 104 and is 5’4, she has a similar build. Bodies vary a lot due to genetics, and fat distribution. Just because YOU don’t hold the weight like that doesn’t mean other women can’t. Some women naturally are that weight and have larger chests and asses while others would not. Also, once again she’s a manwha character and her body isn’t even that over exaggerated compared to others. I don’t think she looks that idealistic.

She’s 164cm and weighs 48kg…? Dawg I am the exact same height and skinny. Ain’t no way 49kg is gonna give you a body like hers.
