Sorry, I know you're trying to show that Zou Yue's parents are caring but I just find them weirdly childish and controlling. They are ways to simple-minded for grown ups.

But Liu Lianyu will make his sacrifices because Lin Jiaen does so as well. You don't need to always see eye to eye to be best friends. You don't even always need to be great to each other.
