I'm writing this review because I want try to help people to understand or to see the ending of the show in a better way, cause I genuinely like the story, including how it ends... So let me explain some points.

1 the end was not unexpected
During the whole show we could see that something bad was about to happen. We have the tittle, the sad songs, the sad Yu Xi Gu’s life story, his health frailty (I was thinking that he was going die of some disease), the fact that he almost had a car accident once, but Hao ting saved him, and the many plans both was doing for the future.

2 Hao ting was the main character, but they both had a mission: to save each other's lives
In my opinion, the whole story is about Hao ting's life and how he will become a better person, and Yu Xi Gu came to help him with that. I think the two characters have a "mission". Yu Xi Gu had the mission to show Hao ting how to be a better person and be a “star” for Hao ting, giving him a way. Hao ting's mission was to give Yu Xi Gu love and affection during his short life, since he never got that from his parents or anything like that. I also think Hao ting's mission was to live the life that Yu Xi Gu lost, making his dreams come true so that Yu Xi Gu could still be alive somehow, even after his death.
For me, Yu Xi Gu was destined to die from the beginning, but having found Hao ting, even after his death he will live on because his dreams will still be alive with Hao ting. So, Hao ting also saved Yu Xi Gu's life.

3 history has a beautiful lesson
I really think we NEED to see this story in another perspective so that we can learn something precious from it: It doesn't matter how long our lives last or how we die, It only matters how and with whom we live our days and make them count.
I'm sure the Hao ting will be cured and we've already seen the beginning of this process at the end of story. Of course he will always miss Yu Xi Gu, but the pain will become a lovely memory.

4 for me, recommending not watching the last episode is a mistake
Last but not least, I want to mention that a lot of people say that watching the last episode is bad and not recommended, but guys, it's precisely in these episodes that we see how amazing Wayne's acting (actor who plays Hao ting) is. The acting is also VERY important to the overall quality of a show, and in this case the overall acting is amazing. So folks, let's properly appreciate the deserved aspects of this work.

Ps: In this show the writer made some mistakes, including some confusing elements related to Yu XI Gu's death, but in this review I decided to focus on the fact that the character died, which was what displeased the fans the most.
