Yang Hui and Xiao Lu. One is a 21-year-old college student, but has a 13-year-old son; the other is a 13-year-old middle school student, but has a 21-year-old father. There is not only family affection between them that transcends blood ties, but also warmth that is more real than love. This is a sweet article with very few ups and downs. I hope everyone will feel after reading it: Ordinary is good!
