There are few things that wouldn't be mentioned much in the chapters so I would be writing them here
First is the time period, here mc is three years older then Ace , whereas Ace is 4 ye older then luffy. I'm putting this so that every one can have a basic understanding of time period and don't get confuse.
Second thing to note is that there would be few changes that will change the original story of one piece, that I would like to cover with other scenarios.
Third is I'm a student doing my UG degree so I will only release three chapters every week.
