i'm kinda disagree about about the author be obsseded with big boobs and ass lmao , if you look at the whole female cast they are all diverse in body type like most of them are average , only fl and the step mom are very idealised meanwhile all the major men from the men cast got the same greek god body type . But i can see where you are coming from about the thin figure tho , but she is korean that how their beauty standard are there and she follows them .
For me, it's not entirely stereotypical but more like distinctions and how the author tries to portrays women to the point it's unrealistic. I'm aware that other people do have this achieved look and thriving at the age of 40 or 50 but still let's be for real, by 40 or 50 you might still look that plump especially on the bust and buttocks area but it's not as super thin as how the mother looks like in the manhwa. Literally the size comparison between her wrist and taeha's hand are unrealistic, I was so surprised because it seems like this mother isn't even eating (built is close to na heeso too). I've been encountering people especially in their 40s and 50s (since apparently I'm part of the cosplay community and it's wild cause you really have to guess their age cause they look so young) but they are really not THAT thin, more like a bit plump or had a bit of chubs despite being depicted thin. I think for me, the author is too obsessed of these kinds of proportions where mostly almost half of the korean population where if you're 40-50s, you'd be a bit wrinkled (even if you took care of yourself) not that plump on the buttocks and bust but definitely thin. But if we're talking about celebrities yes you'll see them have that kind of build. AND even if the mother here is a wife of a mafia—you'd be taking a lot of stress just by dealing family business so I believe it really is unrealistic. Also, there are difference in body proportions every human being especially in races too, so I understand your point that on your relatives, you have someone close to that proportion but if we're talking about african builds, they lean more to that distinct build more than koreans themselves
sure while it’s much more common to see women like that in our communities, women outside the Black ethnicity can also have that body type, even if it’s less common for them look at the ancient idol alice so hee for exemple, sure she is only 25 yo , but even above 40 she can still keep that amazing figure with a decent life hygeine since its very common for korean people tp still stay in shape around that age , especially with how much they take care of themlseves .
I see, that’s fair criticism. But at the end of the day, it’s just fiction, so realism isn’t going to be perfect, lmao. Meanwhile, there are a few minor points I want to mention. About the thinness I think the author added some nuance there. For example, if we look at Na Hae in her smut scene, even though she’s portrayed as thin, she still has a bit of chub on her belly. It’s not as extreme as her clothes might make it look.
Also,i believe wrinkles are very relative . I’ve seen some people young looking people 50s like my mom who look like she is her 30 with barely wrinkles . like she only got just a three visible wrinkles when she is smiling or crying but oustide that it don't show itself that much.
To be fair, even celebrities have very stressful lives with crazy scandals, and the entertainment industry be a toxic workplace to them lmao .
While it’s true that our Africain phenotypes lean more toward a certain build than korea themsleves , it’s not impossible or unrealistic for a Asian to be born with that figure or achieve it with intense Pilates or squats work out. Look at women like Alice So Hee, for example

Haven’t you ever seen a slim woman with a big butt in a tight dress or what ??(⊙…⊙ )
