I just have to say this was a lot better than I thought it would be. The fact that the plot and characters developed so far throughout the story was wonderful, there was a bunch of connections given in reference to how things happened, but I did feel like the ending was rushed and there was some iffy bdsm play things in the beginning (never do those things out of anger, people!), so minus one point. The characters were diverse and relateable. The color changes throughout chapters was really interesting, as was the change of narrative tone as the series went on, as if the narrator and the reader were growing and learning together. I highly recommend this manhwa!
I also have a special message for some comments around here...
[The following is not a spoiler in my opinion because this manga is very clearly tagged as BDSM and Dominance/Subordination, however if you want zero input into details later into the manga, do not read below. It is also a bit ranty:]
...who are feeling like the manhwa suffered a tragic loss because they didn't end on a vanilla note. The couple legit met and connected because of their quirks and their KINK. The most UNrealistic thing would be if they were magically like "oh, I have lost all my resentment so I don't do kink anymore." I love that the manga artist kept in the BDSM characteristic and kink while keeping the characters empathetic, because that is how BDSM should be. The characters didn't have the internet or BDSM forum groups to consult and came up with a safeword on their own to keep each other accountable. I will reiterate that I do not think their BDSM sessions earlier on should have been done out of hatred/spite, and that was honestly hard for me to stomach. However, there is also the worldview of the setting to take into account and the fact that it may have been drawn not only as smut, but to highlight inhumanity through the characters' eyes. I believe the author did a wonderful job. In the end...the characters are kinksters to the core and I love them for it. If you are against the main characters keeping their kinks or kinks being representative of something/someone being "broken"...yeah this is probably not for you and your own.
