Is kinda silly that they didn't explain what happen to the fake sin kei - though it's already end of her that she is paralyzed so they are not going explore anymore. However no one ever know that she died apart from her self, yu chan and chai yuet. Also what happened to her mother - sin yiu father is prepared to be executed and she suddenly disappeared even though she's not an important character. Anyway it is a happy ending but they did leave some untold stories.
