About Your Pride and My Prejudice - Chapter 75: Abel Maurice

Jiang Xun was transmigrated as a cannon fodder. Her mother died when she was young, her stepmother schemes against her, and her father abandoned her in a village. But Jiang Xun didn’t panic, and she was a person who always won by virtue.

Thieves would say, “Stop hitting me, I’ll change careers!”

Thugs would say, “Stop hitting me, I’ll return the money!”

At the Jiang family banquet, guests were watching her every move, waiting for her to make a fool of herself. “I heard that she’s been living in the village for eleven years and has a country bumpkin-like feel to her. If I were the Jiang family, I wouldn’t risk her embarrassing me by letting her attend.”

Mr. Jiang said to her, “Stay behind your mother and don’t speak lest you embarrass yourself.”

Her stepmother nodded. “The Qin family’s patriarch, Qin Mufeng is noble, benevolent, and abstinent. Don’t even think about someone like him; he’s completely out of your league.”

Sure. She didn’t intend to marry into a rich family anyway. She just wanted to beat up the man in the rumors. But why was this man following her around all day every day?

In a world where everyone has a system, Liang Yu, who had lost his previous system, finally received a second one. This time, he was playing the second male lead instead of a cannon fodder.

He has one mission.

Bend the male lead.

Liang Yu: I can do this task just fine. But Lord God, please don’t drop the novel again.
