My husband is back after a three-month business trip. That night, my husband was washing up in the bathroom. But my five-year-old son quietly asked me, "Mom, who is that uncle in the bathroom?" My husband Liang Mu is also a screenwriter and needs to travel frequently for work reasons. Today he is back after three months of business trip. The strange thing is that every time he came back from a business trip, his five-year-old son would excitedly run up and call daddy. But today my son seems to have become a little taciturn.
