Y/n "See you again" (Reader X Avengers)

WARNING~ self harm and does d!e but not by k!lling herself.

Did she do it?

Did she sacrifice herself?
or......
Did she k!ll herself?

Y/n was upset when half of her friends went missing during the snap. Y/n shut everyone out but then their was a way and Y/n knew what needed to be done but did any one else? Did Y/n keep her promise to the team? Did she bring them back? Read to find out.

I own nothing expect some parts of storyline and Y/n she my character she basically can do stuff like Wanda and Buck and is very smart like genius smart like Tony but smarter.
