Im thinking that its maybe the colour scheme combined with the way women are drawn, the anatomy and the perspectives of them in sex scenes which feels like wayy too much (like constant views of the massive chest or ass and of a man groping them or holding them by the hair). Basically you can tell this was made by a man :/

'You can tell this was made by a man’ God, that take is so tired and annoying. You’re acting like the male characters aren’t just as sexualized, and got exaggerated anatomy too. Even in the sex scenes, we get plenty of focus on the men especially Taeha, the author clearly puts a lot of effort into showing off his muscular back and ass. This manhwa cleaely includes a ton of female gaze ( some mincheol panel , tae ha who is sometime drew with a provocative pose , that lee jay fan service scene , tae ha casually having his bulge out in one on art cover..) . Futhemore this is straight smut , of course there are going to be suggestive women boobs, ass shots, are these women supposed to do that fully clothed? . There’s absolutely nothing wrong with ass-grabbing or hair-pulling those are forms of intimacy for many couples. God forbid a woman actually enjoys having their ass gropped and could enjoy their hair pulled by the man they desire . its not objectifying or problematic as long there are consent involved, Your comment sound like you got problem with women 's sexuality and puritain mind about women's body.
Yes, there are some icky scenes involving Mincheol, Taehee, and Micheol’s colleague but the author clearly condemns these behavior , the way it’s written makes it obvious we’re not meant to root for how they treat women. tae hee and mincheol are clearly potrayed as jerk for a reason

My problem stems from the anatomy in combination with all that. There is nothing wrong with a bit of hair pulling a groping obviously but in this with her being so small those scenes feel somewhat threatening with how they are portrayed. You are selecting certain things i said when i am talking about it all in combination being what is uncomfortable. I wouldnt be reading smut in the first place if i had a puritan mindset about womens bodies, i have read plenty of all types of smut and plenty with which i dont have such a problem.
The problem with alot of straight smut and yuri too is the objectification of women that systematically exacerbates real life objectification of women, and that type of media has been typically made/influenced by men. And you cannot for a fucking second compare female gaze scenes to male gaze scenes in this. Yes male characters are also sexualised, but they are not just as sexualised as women, and probably will never be.
Anyway this was my opinion, you do not have to agree with me but just think about it abit.
Im in this for the plot but have to say each time i read it i feel so icky afterwards
