Is the ending of I am Yu Huanshui life or death?

I'm Yu Huanshui. This play is really good. The process is ups and downs, which is thought-provoking. It's really a counterattack, but personally, the ending is not particularly good. Of course, it may be for some purpose that the ending must be complete, but one thing is certain. Because it was later discovered that it was misdiagnosed, she said that she didn't have cancer and was in good health, so the ending must be alive and nothing happened.
