I had to drop this series mostly because I just can't stand how toxic the relationship is. It's basically a relationship between someone who is constantly verbally abusive and takes advantage of their partner, never being honest with themselves and taking every opportunity to get out of apologizing and someone who is overly forgiving.
No matter how bad it gets Dojin forgives Hye-Sung for literally everything. It honestly just pisses me off.
If you can get past that part of the character design then go for it. The story has great detail and their journey would be cute if there was some character development, but I made it halfway through and they're still exactly the same, just living a different lifestyle.
The sex scenes are hot though, and the art is really well done. Sometimes in color, sometimes not.
