Male artists usually draw hot women and bland men, female artist usually draw hot men and more bland/normal looking women (not always ofc), so the mc is more relatable to readers.
In this manhwa, mc does have large boobs but I think it's because she's supposed to be relatable for older 30+ women, chubbier, not slim like young models.
That's a good point you are making . Also in that manhwa you can tell that it's artist who love to draw both gender on juicy way, every major character are hot , both mc and fl got the equal fan service treatement. But by the way the all the men cast are drawn you can tell that it's 100% a female artist, espcially how most of the cover art were about tae ha be sexy and the focus and angles they got during sex scene as well , no men is drawing a erotica like that lmao

The art is too good to pass up
I dunno if it's confirmed somewhere but I can tell the artist/author is......a guy. Yeah iykyk
