I forgot to write a review for this story when I first read it, but I've reread the first and last arc and generally remember the rest of the book. I quite like the novel - it has pretty interesting, unrelated arcs where the ml seems to have slightly different personalities in every instance. The wrap up explanation is very cursory, but that's understandable in a short novel like this one. I like the slow burn in each story. I'd say that the arcs have a good proportion of plot to romance. Since there's only 4 arcs, it never gets to the point that the Mc gets through arcs purely based on love (unless you count the way he manages to skip the bulk of his points gathering due to the ml).
I don't think there's any big moral or story in this novel. The stories about zombie animals, vampires, mermaids, and ceo are really unique. I think I like the last ceo arc the best.
