The friendships between all four characters were spot on and I never knew what was going to happen. That itself made the series very addictive (I finished it in 2 or 3 days).

Li Yi Tong was spot on the entire time; she's badass, rough around the edges, yet grows and show her vulnerable side more as the series progresses. Li Jie was kind of a nuisance at the beginning, but later shapes into a more responsible, character (yet still maintains his boyishness). Zhang Yubo is a little cold at the beginning, yet his transforms into a more caring one as his friendship/relationship progresses with Xiao Jiu. Xiao Jiu was the only character I did not like as much relative to the other three. She kind of getting herself mixed up between pursuing Yubo and trying to save him at the beginning. She makes Yubo the center of her universe too much and is annoying was she cried/gets upset. However, I did like how Xiao Jie showed determination as the series progressed.

Nevertheless, there were a few things that I did not like.

1. It was predictable that Fatty was up to no good almost the entire time.
2. I wish the drama between Yi Tong and her mom was played out more.
3. The end was a little confusing imo

Definitely would recommend this to someone that is looking for something just a little different (but not super different)
