This is a really sweet show around growing up, friendship, family, and love.

A bit slowpaced, without big conflicts or "villains", mostly feelgood.
There are some very heartwarming scenes, like between Guang Feng (?) and his grandma, and the small gestures from Rangrang showing us how he cares about her.

The ML's role is kind of similar to that in "You are desire" and the same of his friend (Gu Ran). I like both of their acting - suitable roles.
FL is very sweet, although I do find the female characters in Cdramas often to be a bit overly childish.

I can see myself recommending this as something to watch for a mum (/parents) and teenage (daughter) together.
