Before Li Wen found Andrea in The Neptune Trader, Yeong and Lu Fang had already trailed Anges Dronne Duval in Paris.
Anges and her family were the owners of the clinic back in Molène island. To Lu Fang's point of view, she was equally accountable for what happened to his wife. He was positive; she knew of her husband's doing, somehow.
When they approached her, it surprised them to see how inviting she was. She pretended to be shy and demure but all it took was Yeong to ask, "Do you want to have a good time?"
She willingly agreed. Due to her husband's usual absence, she slept with different men occasionally, but she was choosy. Only young and handsome men get to be in bed with her. She was very discreet about it, but unfortunately, she was already under Li Wen's surveillance when she indulged while her husband was away.
