Alone No More (Leo Alvarez X Male Reader)

It's been a year since Chase broke up with Leo. Leo didn't handle it every well, struggled with depression and slowly became infatuated with delusion. When passing through Echo, in order to drive to Payton, Y/N's car breaks down and the nearest auto shop is the only one in Echo.

Leo is the only mechanic for today and unfortunately for Y/N, he resembles Leo's long lost lover. Will Leo use Y/N to fill the void in his life? Or will Y/N either help Leo overcome his delusions, or become the moulded idea of Chase that Leo has become infatuated with?
