Foot Wash at Best Friend's Wedding

At my best friend's wedding, my best friend's parents stopped the groom when he came to the door and forced him to drink the best friend's foot-washing water. They also said that he would not be allowed to pick up the bride if he did not drink it. My unassertive best friend kept asking me for help with her eyes, but I turned a blind eye. After all, in my previous life, I helped her shield her parents from troubles, but she blamed the family discord on me for not letting her husband drink the water for washing his feet. In this life, let her see if a basin of foot-washing water can bring about family harmony.
