***with SPOILERS***
Throughout the novel, Di Yun (Cantonese: Dik Wan) was "in love" with his sister-at-arm Qi Fang. Right up until the moment she died, he still thought she was "the one."
However at the very end, it was Shui Sheng who waited for him when there was no one else left. The novel ended with her happily running towards him, and presumably that was the birth their future, though we didn't get to see any of it.
And yet, even when the novel ended, he still haven't gotten over Qi Fang. Maybe he got over her later, but we didn't get to see that.
So I ask you, who is Di Yun's true love: Qi Fang or Shui Sheng?
