From what I read this is nothing more than trash, I actually dropped it at some point.
Has a nice art style, but the merits end there.
Usually I really like a bit of twisted but some-kind "psychologically justified" or violent behavior, but only if this behavior is seen for what actually is i.e. not positive, not right, not romantic.
I give 2 example: in painter of the night

the author made it quite clear that any of those was because of romantic circumstances;
in killing stalking the author makes sure you are fully aware of how sick the relationship between the two protagonists is),
Then we go to this manhwa: it's like the author want to justified horrific actions, financial dependence, domestic violence, segregation, stalking, multiple SA, etc.. as a form of "extreme jealousy", like "he did what he did because he loves him", the mindset here is so wrong. 

I also see the glimmers of this toxic mindset in some comments below this and many other manhwas.
Like when readers say they find possession (seen in a limiting way) hot,
or when they really hate protagonist1 (when is not in a relationship with anyone) because they kiss or else with someone that's not protagonist2,
when they think a person love someone because you can see they're super jealous...
Well this is dangerous, especially for young readers.

(Just a reminder, it's perfectly fine if you will have more than one love interest and will experience intercouse with more than a person in all your lifespan. This is actually normal in the real life, at least where I live, I could say a thousand more but then I will go even more off topic,)

in conclusion,
I not recommend this manhwa to a single soul and to those who have unfortunately read it, i wish them to forget about it like you do with nightmares when you wake up
