Author's Comment from First Chatper:

Yes, this had chapters before. Yes, I did a bulk release because I had written so much and I wanted to make it easy for myself but it was easy for me to read because I knew everything I have written. Also yes, this has different worlds. For now, I have written an Arc for Naruto, then MCU, and added elements from Final Fantasy along with Nier Automata. If you don't know it about these then don't worry. I don't info dump a lot. You'll get used to their characters and I don't run through the story either. Moving on to the topic of NTR and Netorase, keeping reading.

For those who hate Netorase/NTR type anything. Keep reading.

About Netorase/NTR:

Let me make this clear. I have walked a fine line while writing this novel, it's like NTR but not NTR and it's not Netorase that you usually see. I am tired of these doujinshi or novels where Netorase means that the guy actually has a micro-dick and he's fucking pathetic and some kind of bully is fucking his wife up and then she leaves him for the bully. Yeah. This is not that. (Frankly, the people drawing this shit don't understand what Netorase is about. Or atleast my view on the topic is different from them)

This genre is like incest, you don't do it in real life but because it's forbidden and wrong it's fun to read. Don't be so serious about it. If you still give give it a try. I promise. You will enjoy it. It's not meant to make you feel bad about yourself. It's written to make you enjoy what is forbidden, too forbidden without all the pain that comes with it.

I know, it's a fine line. That's why it took a long time to perfect it.

Anyway! Give this a try.
