Is Yu Huanshui's finale implying that what happened later is just his fantasy?

Hello, I'm Lu 'an, and I'm glad to answer here today: It's not fantasy.

With "I'm Yu Huanshui" being brought deeper and deeper by the plot, Guo Jingfei's superb acting also made everyone fascinated. Guo Jingfei vividly interpreted the hero in the play, just like some people in our lives. Now the TV series has ended, but many people said that the ending is incomprehensible. At the end of the play, Yu Huanshui knew that he didn't have cancer, and he became a great hero to help the police solve the case. He also got up the courage to confess that they were happy together with Luan Bingran. As the wrongdoer was arrested, he also took the position of general manager of the company. All this was very successful, and no accident was coming. But it's reversed. Yu Huanshui's last confession in the play is somewhat incomprehensible. Yu Huanshui said that he is not sure whether all this is true or not, or maybe it is a fantasy, but he told himself: Do it again anyway, which is very suspenseful.

In addition, because he took the wrong case and was misdiagnosed as suffering from cancer, he planned to give birth to him lightly, and he became a hero who saved lives by mistake. At the same time, the hospital packaged him as an anti-cancer fighter and made many speeches. In this story of repeated mistakes, it seems that he is about to turn over. However, he was kidnapped by a group of criminal gangs for revenge and taken to an abandoned boat in a tourist attraction. The most wonderful dramas took place in this boat. In his unparalleled eloquence, he outwitted several vicious gangsters. In the end, he led the police to this place through organ trading organizations, and the criminal gang was completely destroyed. In the last part of the ending, Yu Huanshui married Luan Bingran and was promoted to the general manager of the company. If he only played here, I think the ending is reasonable. After all, this is what the audience expected. However, when Yu Huanshui walked in the street, he suddenly made a confession and made the plot move towards an open ending. So, was the last fantasy denied by himself?
