Li Yifei felt that denying it at this point was unnecessary. The main thing was Xu Yingying must not find out, and his sister-in-law Xu Shanshan, who always had a good relationship with him, might be convinced to keep it a secret for him.
Once a man got married, his mindset naturally changed. Before marriage, he needn't explain who he was with to anyone else, nor fear being discovered. But now it was different; he absolutely had to hide this from his wife.
"Shanshan," Li Yifei put on a flattering smile and said to Xu Shanshan, "Your brother-in-law made a mistake. Could you not tell your sister?"
Xu Shanshan grinned and replied, "How could that be? She's my own sister, we're siblings from the same parents. If I help my brother-in-law cover up his infidelity by keeping it from my sister, wouldn't that be turning my back on family?"
Seeing Xu Shanshan's attitude, Li Yifei felt reassured. If Xu Shanshan had shown anger, he would have been in more trouble.
