Notes:
This book is a fanfic focous on Marvel. They not gone folow necessarily the UCM, but it will have influence.

This novel is BL so for those who don't like the genre, I don't recommend reading it.
The protagonist will be OP, but will have growth.
The posting rate should not be very regular as I write other books and have other studies and work.
Hope you like it!
