Story for chapter 1 has an interesting plot, with intrinsically flawed characters, which is great, I love how it seems character progression will drive the plot here. Besides, the art is high quality too. Mostly read action and fantasy but may check this out.
I still remember reading about Kaneki possibly being able to eat cum too besides human meat and how "guzzling cum" would not make for good content so that might be why that did not happen...
