ISO Avengers Rogers/Lewis fic

I'm a reddit lurker so not sure if I'm doing this correctly but I read a fic a few years ago that I have consistently thought of since.

The fic is a Steve Rogers/Darcy Lewis ship and starts during the chitari invasion of NY. Steve experiences a groundhog-esque reality in which sometimes he relives just the same day and other iterations experiences years before his time resets to the start of the invasion.

I am 99% the fic was completed and I don't remember title or author. I've looked for the fic a few times and haven't been able to find it so I thought I'd see if it rings a bell for anyone else.

Please help me find this fic!
