The fate episode of the warrior Lan Ling: I belong to your fate, but not mine.

I think so. In grandma's divination, there is no warrior Lanling in Yang's fate, or there is no fate, or grandma didn't choose to tell her the truth in order to protect her, but Yang rewrote his own fate, and the fate of warrior Lanling just doesn't belong to me. Your fate is Yang's inner desire for the fate of the warrior Lan Ling, hoping to rewrite the original fate, which belongs to her decision. I think that's what it means. This should be a very happy change. I don't think it's sad, although the song fate looks sad.
