No doubt the best BDSM manga/manhwa out there, maybe even one of the best yaois.
I love Shell and One's relationship, the sex scenes are phenomenal and they have so many great fluffy moments. Shell is so adorable and I love the funny moments where he gets really clingy with One. I like how One gets exasperated with Shell, but it never ruins their chemistry or seems abusive. And speaking of abuse, the BDSM between them is great because it never gets really abusive and they have a safe word which is great! The times that there is abuse, the story doesn't glorify it or paint it as something desirable.
The atmosphere and art is amazing. I love the steampunk aesthetic. The outfits, settings, and color choice are all so good! Shells facial expressions are the best part though :L.
The story is great and gets dark at times. The world building is good and I appreciate that the author put some real effort into it instead of just focusing on Shell and One's relationship.
This is one of my favorite manhwa of all time and I highly recommend it! I am eagerly awaiting this artist's future projects.
