With his engagement at hand, the most terrifying and legendary person of the legal world, Fu Huai’an, returns with a son.

Before the engagement…

He asks, “Since you love Wen Moshen, why are you in my bed?”
She says, “Because I cannot watch idly as Wen Moshen’s woman enters an engagement with you.”
