This is a story about growing up.
Bei Xiao was born in a wealthy family. Because of his father's squandering, he was "not rich for more than three generations." But it doesn't matter. Under the protection of her family, she has lived well in the past twenty years.
After going to college and entering a small society, she became more and more casual and indifferent. The day passed by eating and drinking.
Suddenly one day, she realized that she could no longer go on casually. She is not a casual person after all.
