I dont hate the way this ended, I actually enjoy trageic endings as it allows me to feel. In all honestly it feels like the author butchered the ending and wanted to close character events quickly without fully exploring what has been introduced. I've noticed this is a problem with alot of authors who include Erotica, sexual violence, and so on. They cant quite seem to nail the endings properly.
The scummy MC was a change that I welcome and with him losing pretty much every girl as a lesson to not be so shitty, especially the one who loved him the most. I just wish it was flushed out better I cant rate this higher than like a 5 maybe a 6.
