Why the FL have to be so childish

I have tried watching this drama and ones like it but I just can't with have the FL be dumb and childish. Love Xu Kai in all his roles todate. Struggle to watch this because the FL is really getting on my nerves. Please who ever write these drama's can the FL start out as a strong woman instead of a child. I have read reviews on this website for the past 2 years, and after watching just 5 episodes I had to subscribe to write a review because this took the cake and I waited for this drama to come out. I guess I will have to wait for Best Choice Ever.
