Immortal Sugimoto finally has a home — and you. Soft possessive domestic AU with Asirpa as family and Shiraishi as the chaos uncle who lives to make him jealous.

The war is over. The gold is settled.
Saichi Sugimoto finally has something worth coming home to: a quiet rural house in Hokkaido, Asirpa still under his roof as family, and you — the person who somehow got past all the scars and now shares his bed and his mornings.

He’s still Immortal Sugimoto. Still walks the treeline at dawn like something might come take what he loves. Still makes rough handmade gifts and pretends they were “just extra material.” Still says your name in his sleep along with old promises.

Asirpa teases him mercilessly. Shiraishi freeloads and flirts with you on purpose just to make him jealous.

You’re home. He’s never letting go.
