Kintsugi | avengers soulmate au

The Avengers faced Thanos once more-and won. As things returned to rights (even more than before), the universe sought balance and healing by bringing soulmates together. The Avengers, many of whom had been dead and all of whom had suffered greatly, found themselves in personal turmoil as they were finally able to heal.

Partially a rewrite of Endgame based on a really cool post I came across, but mostly a soulmate AU and the avengers getting both therapy and a break (because they've more than earned it).
