Definitely puts the dark into the dark romance genre. This IS NOT a light read. While it contains FL being SAed multiple times in graphic detail, it is not even the tip of the ice berg with how many fucked up shits going on in this story. However one good thing about this story is, it very clearly shows how long term abuse affects the victims in a very detailed way instead of glossing over it like many manhwas often do. You can see how every decision FL makes is tied to her being abused and abuser so i think it gives the story a veryrare touch of realism.
There wasn't one happy moment in the whole story which honestly made me want to bash my skull with how much angst was going on but i would say it is also very realistic in that sense.
While i think this is one of the few REAL dark romance manhwas with realistic end i don't think this can be read for 'fun' since this shit genuinely made me want to cry. I would say be very cautious while reading it because it contains every trigger under the sun in it and maybe some more too.
