A lot of people out there have constantly said Zheng Shuang is bad at acting, but after watching this show they may change their minds. Keep in mind how difficult it is to act a character that is going through hardships.
Back to the ACTUAL story though:
Meaningful friendships and relationships portrayed throughout, if you stick to the end, it may make you feel empty but full (I know, awkward right?)
I must warn you it's more sad than happy, but hey, if it's that your style, go for it ;P

Anyway,
I would watch it again to see the story from another perspective, and to see the actors acting together (cause the main leads are so cute together), but I would skip through some of the brutally sad an powerful parts...
