Yeah I definitely think they could've done the drama without having her have sex or relations with the instructor. The Male MC isn't all at fault but obviously she has reason to be annoyed that he wants her to not be with others when all they have established is a relationship if FWB. THOUGH. Do I think shes a bit shallow for breaking up with her bf for sum cock. No not really. Sex is important for some of us to that extent lol. Anyway yeah. I think this story can get better but you saying she goes back and fourth definitely makes me reconsider continuing the series the only reason I really read it is cause of the author's previous series.
Yea i like the sex to be just between the two mc, i mean they are going to be the main couple in the end. I'm ok if the femele or the main guy had partners at the start of the story even having sex with them. But that is just at the start, later they break up, how the femele lead did. What i hate about this type of story that i seen in other manga/manhwa is that there is no communication. On the korean site you can read only if you pay but you can see images from the chapters and it seems that she's going two swich between the two of them.

Honestly I think this is just always a romance drama thing there is always most likely never any communication between the couple and its soooooo annoying I dont get why that's a trope it's literally more annoying and lazy then engaging and interesting
I hate when there is no communication the most. You can have a good romance story without drama, just focus on the main couple story. For exemple Horimiya where you have the main couple story and secondary couples or tonikawa where is the couple every day romance. this are non hentai manga/anime that are realy good.
And for a hentai manhwa i recommend Childhood Friends is vanilla amanhwa about two friends who become lovers without harem or ntr and bullshit drama.

This manhwa is trash for me, it has unnecessary drama. The main characters don't communicate, the female lead wants the main guy only for his big dick, and the main guy is a big idiot.
SPOILER the female lead has sex with the swim teacher in chapter 22, she is not cheating because she and the main guy are just sex friends, she is not a slut ok, having sex with another guy doesn't make her a whore. I just don’t like it, and is the same scenario if the main guy was having sex with others girls. For me it is nothing but bullshit drama. A good romance is done only with the two main characters and with side characters as the support for the main ones or as secondary couples. When you have one of the main protagonist have sex with the side characters is just to piss of your readers. I saw on the korean site that the main femele is going to have sex with the main guy in chapters 24-34 then again with the swim teacher. But i'm sure that the main characters after some more shit drama are going to end up together at the end. IF you like this manhwa ok for you but for me is not a good romance it is garbage writing.
