Across The Universe (ToshinorixReader)

Synopsis:
This is insert your name type Fanfic. Main character is female and super OP. She does have her weaknesses just warning you she is OP. Explanation of her powers later on as they are part of the story. She calls them powers too not Quirks, you will see why later.
This is my first time writing and sharing a fan-fiction to the public. I would appreciate any constructive criticism like how to make the story flow more or any grammar issues I may have missed.
The character is OC, rights to me so none of her backstory and powers are changeable.
For more information on my OC I will make sure there is a link to the description and drawings. That might happen slowly though because I want to write this up first.
WARNING: There WILL be explicit material and scenes. It will take a while to get to any explicit material. I've found that Wattpad seems to allow detailed scenes, but this is a romance story first. When I get to said scenes it will be clearly marked in the chapter contents with like a * or something. And there will be warnings prior to the chapter start.
There are some musical scenes but I can't add the music I don't think, so I'll just be sure to write out the musical piece and author here and in the chapters they are referred to.

Edit: I have rewritten Y/n to give a character name just because it's kinda difficult to write a character with no name and feel an attachment to them. Please still insert your own name and colors or whatever you feel you want for the story.
I feel it's easier for the story to flow if you don't have to read over placement text like that. Just a heads up in case you see some changes.
Thanks for reading!
