Heartbreaking to watch Lusi crying

Excellent acting from everyone. I am into modern dramas but watched this just because of ''Zhao Lusi ". How can she make everyone cry when she cries?? Excellent dance performance and graphics. I am all for a happy ending, that is why I gave the story 8 stars.
No one can be better than the ML for this role
I cannot imagine anyone else as the ML for this role( May be Leo Wu look good) .
I cannot rewatch this because I cry with ZLS and will break my heart again.
