Basically the protagonist Cheong-ra is a martial artist from Moonlit sect while Dang Ran-yeong is a bit of an controversial figure in the cultivation world who knows how to use poisons, they have various encounters like their first one and then join forces to eredicate an evil cult, the plot focuses a lot on the protagonist's sexual fantasies (who secretly likes being manhandled and violated) being heavily conflicted about them too, while they slowly get more close to each other because they match each others freak he's also ashamed of this, I haven't finished it but I think it's interesting however having advanced in the novel I have to admit it's a bit too harsh even for me, since the manhua usually cuts out some parts maybe it will be a bit more lighter

Ah... The novel goes in so much depth on what the main character is feeling internally, I guess it's all cut otherwise there would be 30 bubble thoughts of him jist explaining his deep desires about being hurt and overpowered but if anyone is into this go check it out on novel updates (to read you need to make an account):3
