Gu Yanran is very satisfied with the younger brother he raised.
Gu Yanbei: Whatever my sister says is right!
Gu Yanbei: My sister is so easy to deceive, so why don't you go out and make a fool of yourself. I will take good care of her from now on.
Gu Yan later found out that he had led the wolf into the house and regretted it.
Gu Yanbei: You raised me, and there is no one in this world who is more in line with your wishes than me.
Gu Yanran: What I regret most is that you were too thick-skinned.
