The plot of this manga is incredibly good. All points tie so neatly together. The host setting is also exceptional.
However, be wary. Kiichi starts off as one of the crappiest noncon dubcon toxic guys ever. Sure though he does warm up over time, and the plot reveal behind his feelings do kinda add up (some people become horrendous when not given approval).
What I like though is that Ray is given leeway to get angry at Kiichi and absolutely insult him for his deeds. Good on you Ray, and I felt so bad for him!
Overall: Good plot but has very toxic start
