A Butterfly That Brings Fear: Aether Contract

After leaving Teyvat with his sister to return to their home, the male suitors fighting for Aether's heart lose their minds, and go to war with each other, each believing the other has him. Albedo, while wallowing in his misery, makes a doll just like Aether, and this makes everyone go insane to get it. When Aether returns many years later, the place he once called home is a wasteland. Yet the men still live on. Can he survive?
