Pulsatilla, when I was a child, I heard from my mother that if my wife died, Pulsatilla would go with her. He turned white because he wanted to spend his life with his partner until he was old.
Story, a beautiful story, may not be as good as Yuanyang:
If I hadn't just heard the story of Yuanyang, I might not have thought of Pulsatilla, haha.
