Harry Potter: Lost in Time

Yes, the whole story is written around Li, and Ruan seems to be invisible, especially at the beginning and end, Ruan is like a supporting character.

The main thing is that I didn't want to watch the first part of the movie because the relationship between the characters was simply too confusing. Really, there are too many characters and it's too confusing. I have no interest in reading it at all. I could still coax myself to watch it, but now I can't coax it any more and I can't figure it out at all.

There was basically no mention of Yuan when they were talking. Although they were twins, it felt like Li was the only protagonist.
