I love it, very good job. The story, art, characters... everything is great, this visual novel is a good discovery.
The only drawback (for me) is that the MC is, like most VNs that I have been able to play, sub bottom. As a top, it shocks me a little to read certain parts of submission and being a bottom.
The same thing happens to me for example with "Far Beyond the World".
It is true that, as has been said in a comment below, there are more VNs where the MC is top (or it is possible to be top), such as By Your Hands, Lust Odyssey, Lustful Desires, Small On Top... But I have played many more and the majority are usually a sub bottom MC.
But outside of all this, thank you again very much for this great VN, highly recommended!
PS: My fantasy would be to have Cadgan and Ranzkai in 4, that would be wonderful (yes, I love big bottom dudes)
