   Summary

   ❝They call it devotion. It looks more like obsession.❞

   Y/N lost everything at eleven, then found a new family on a mountain. But when tragedy strikes and she loses her second family, the survivors choose their own path.

   Hidden away, growing stronger, guarding a secret that could get them all killed. And as their little group expands, one thing becomes clear: every single person who stands beside them would burn the whole world down just to keep Y/N safe.

   ⚠️ Yandere!Various x Y/N • Goes fully off canon • Slow burn • OP Y/N • Hidden breathing style revealed later
