I added some manhua in here as well, if that's okay.
Webtoon - He is forceful at one point, but he doesn't rape her. And after that, while he might pull her close for a hug or anything, he never forces her to do anything she doesn't want.

Webtoon - A cute read with some cute tsundere interaction.

Manhua - Some tsunderes. It was a cute read with some good drama.

Webtoon - While it has your stereotypical evil sister and whatnot, the relationship with the male is consensual. He gets on her nerve, but it's consensual. He even tries to get her to stop coming onto him when she's drunk because he doesn't want to take advantage of her.

Manhua - It was an enjoyable read. There's a sequel, as well. I recommend it overall.

Manhua -While romance isn't the main focus, there is definitely romance in it. They're a nice couple who respects and truly loves each other. This has to be the best manhua I have ever read.

And then I'm sure you know about the webtoon 19 Days, which was previously mentioned here.
My top recommendations are Wo zai hougong dang ju ju and Oldman. Now that I think about it, I recommended 19 Days because I enjoy it. There is actually a lot of non-consensual stuff with the secondary couple. People ignore it, but there's straight-up sexual assault on multiple occasions as well as plenty of sexual harassment.
Is it me? Or I really dislike reading Chinese webtoon? Not only are they terrible, but I hate how the mail female lead is always fucking abuse or raped or murder or something awful. And then they go and meet another awful person who does the exact same thing to them? But not only that the plot is EVERYWHERE! I just can't stand that shit. I hate it how every time I see the Chinese webtoon and read a couple chapter it always like that.
This is my opinion
