WILD!!!!

Just finished watching this on iQIYI, that was wild!!!!! (in a good way), the acting is really good, the actor who played Shenqi didn't even have his own mydramalist page and yet his acting is really really convincing! The dialogue flow naturally, the twist and turn in the story are all making the whole movie even more interesting, the two actors are cute, Oh, and the main girl, the chubby one, SHE'S THE LOVELIEST OF ALL I WANT TO HUG HER!

How is this rated 4?!!! I don't understand the rating at all...
