This is one of my favorite BL manhwas of all time. The art style is beautiful, and all the characters are really well thought out with reasonable motives for why they do what they do. I think this manhwa handles heavy topics, such as slavery and classism in a realistic, graceful manner. The relationship between the two leads is developed at great pace, and the conflict of interest of them originating from two different species is never glossed over. I would definitely recommend this as a read to anybody interested darker BL stories.
