If you want the rating to be stable at 9 you should probably verify your account then vote, the verified rating is low compared to other dramas with a 9+ rating. That might be what's affecting it.🤷🏾♀️
For the deliberate haters who didn’t know this: TFF was Zhu yi's first novel and later on HL(secretly, secretly…
Just to clarify HL novel was published first, you can check the douban links below but it's no doubt that TFF novel has a larger fan base hence the drama's budget. https://m.douban.com/book/subject/35003286/ https://m.douban.com/book/subject/35296868/ While watching the dramas you can tell the writer wrote HL when she was younger/had the idea in mind when she was younger. For TFF it has a more mature feel to it.
What even is the point of the mom reuniting with her daughter, relearning how to walk and getting married to Mr.Yuan, all the things she desired just to die such a useless death?? There's enough sadness already, bruh they really pulled a TSOPG on us.🤦🏾♀️
