For me it’s watchable every episodes since you're didn’t like first 4 episodes then I suggest to watch from episode 10. It’s getting better every episodes. Most importantly Xiao Zhan acting improved alot.
It's definitely not an 8. Some scenes are unnecessary or awkward. I find myself asking these questions while watching…
Ren Min still looks young. She is even younger than me. When this drama shooted her age was 21/22 years old. So, her high pitched voice i can considered because she looks young but big girl act and voiced like baby i can't consider.
E.g. Shi Ying, Zhi Yuan, Chong Ming, Qing Gang
