It's just loose skin
Almost all women have them after a certain point, especially women who give birth and lose weight afterwards.
That doesn't make sense tho. She is in the "youthful super skinny" version of her body. Even her crow's feet and eye bags dissaappered, and her skin is super tight. The only difference is that part.
Babe, I'm 25 and even I have those
A woman's body changes a lot throughout the month, you get bloated and then shrink down in a matter of days. Loose skin and stretch marks are completely natural.
Girl...I never said those weren't normal or natural or whatever.
I have stretch marks and loose skin too.
But this author doesn't draw those. Not only do manhwa author's always erase away little natural "imperfections", here she is supposed to be a super idol whatever. And that was her first time seeing herself back to her youthful "perfect" self.
Why can you see the ribcage tho
Do older people show more ribcage??
