Review Detail of Psygone in My Grim Reaper

(Thanks for the new waifu btw) This novel, literally, got a totally brand-new plot. The protagonist (Cain) finds himself interacting with a Grim Reaper (Lorelei) so both of them could get what they want. Writing quality is decent, the plot is engaging, however it lacks a bit of world background (it still has 3 chapters so that's not really a lacking tbh) Good job, keep it up!
