Time frames [Ace? Marco? x Reader]

Intro

This is one of my first stories, from when I had just started writing in English, and it's unedited. So please forgive the horrible writing.

I'll come back and edit it sooner or later.

Hum, okay, so it was supposed to be a one-shot, but I'm just not able to keep things short, apparently. It will be just a two or three-part story though.

It's based on a request made by @lyndsyh. Go check her works, if you hadn't, they're awesome.

As always, sorry if there are some grammar mistakes, English is not my first language.

I'm not satisfied at all, but if you bump in this fanfiction and you like it, feel free to leave a comment or a vote.
