When a group of brats live together, they don't have to worry about money, fame, and life. You can make as much noise as you like, and the most you can do is get a spanking from your dad when you get home. I still don't understand love, but I have a good impression of someone, but the good impression is usually not mutual. Who says that if you love her so much that she doesn't care about food, she must like you? So there is bitter unrequited love, and there is more than one line. Moreover, there will always be someone who has a different meaning to you. How many years can you call him "buddy"? How many people can hang out with you all day long just by calling your name at the door during the dog days of summer? This story tells the story of a group of unexperienced and quirky little kids, and various things that happened when they transitioned from children to teenagers. The background is an alleyway in Beijing in the 1990s.
