I don’t agree

"Can you really do it?" Old Madam Murong asked Murong Si as she took a sip from the hungover soup, she looked at her son and waited for his response. In fact, she really hoped that her son would be able to attract the attention of Yu Tong such that the mer who had caused them to lose their faces would learn his lesson. 

Once he was used and dumped to live in the house without the affection of his wife, that mer would learn his place. After all, a useless mer like him should be living in a tavern where he should be selling his body instead of marrying a decent woman like Yu Tong. 

Murong Si looked at his mother who was staring at him with a stern expression and smiled at her. He tucked the strand of her light brown hair behind his ear and then replied, "Of course Mother, I will make sure that the Yu family will not only be respectful towards me and you but also make it certain that the mer who has stolen my place would learn his place as well."
