Kneeling down was obviously just teasing, but when it came to calling her sister-in-law, Xi Muchen was serious, and Wei Yan could tell. It's just... calling such a young girl who looked several years younger than him sister-in-law?
Wei Yan expressed his strong desire to refuse! He said with a look of grievance on his face, "I am... older than you, and you want me to call a little girl sister-in-law? That's not fair!"
Xi Muchen arrogantly lifted his chin, "What's wrong? Does calling my wife sister-in-law humiliate you?"
Wei Yan had just nodded his head, wanting to say it was humiliating, when Xi Muchen continued, "Even if you're humiliated, you still have to call her that. Who was the one who lost the fight that year? Who swore, 'If I lose, I'll call you big brother and be your little brother for life'?"
Wei Yan: "..."
