series: Purimu no nikki
Spoilers ahead so make sure that i warned you:
I would change place where main character acts all pussy like and decides not to go after lovely Purimu to rescue her. Also i would change NTR part of series since i think that doesn't belong there (mainly rape part where Purimu gets raped by wizard pretending to be her master).
PS: its very sad that one of my most loved series had this kind of content, im still pissed off by it, i think main character should have more "balls"
