At the beginning
Baby Zhu: Chasing stars is such a sweet burden, I just want to be more enlightened
Cai Zeling: I'm just a cold superstar, but when I see her I can't help but laugh.
Later
Baby Zhu: Ah, ah, you have changed. You are no longer the person I know.
Cai Zeling: Baby, what are you talking about? You have always known me.
You and I have nothing to do with each other. Our fate depends entirely on Brother Cai's hard work.
Not stupid but white little sweet bean, a daily fool VS a big star who can be aloof, yet warm and affectionate, making fun of the little fool.
Purpose: Every little thing in daily life is the happiest thing
