What’s with all these C-drama heroines all acting like kids?

I liked it and yet I didn’t like it.
I loved the ML, XIAO Zhan set my ovaries on fire and that’s no joke,
This is the first time I’ve seen him in a drama and he blew me away.

I’m very new to C-dramas but I’m having a lot of trouble with them, they start out so great but then they just seem to drag with unnecessary drama.

I’ve noticed a lot of the FL characters are the same or maybe I just keep on picking the wrong dramas, why are all the heroines dumb/artsy types/and so bloody whiny?
I’ve seen this FL in 2 dramas, this one and Go Go Squid(which I dropped because it was unbearable) she was the same in both. Didn’t show any acting chops honestly.
