Xiang Xiaoyuan transmigrated to a book with a male lead, becoming the male lead’s stepmother.

However, being seventeen and in the middle of his adolescent phase, the male lead virtually ignored his stepmother, and while his father was thirty-nine and a gorgeous man carrying maturity and elegance, he was enigmatic, with no one capable of knowing what he’s thinking.

Xiang Xiaoyuan: The first rule of transmigration, value your life and stay away from the male lead! Being self-conscious, Xiang Xiaoyuan decided to focus on making money, and her business was booming… but before her hopes to get rich were fulfilled, she somehow dealt with her husband and stepson?

Xiang Xiaoyuan: “…Thanks.”

Some other day, her husband stood at the doorway, stopping her and growling, “I heard about something you mentioned outside, that men only care more when they’re older? So? Are you complaining that I’m old now?”

Xiang Xiaoyuan said, “…Wait, listen to me!”

Lu Wanggui: “???”

What’s going on? Weren’t things cold between these two?

The son: “Ahem. Father, Stepmother… isn’t that bad.”
