The silly young master suddenly stopped being silly. What is this?

"Silly young master is suddenly not stupid" means that silly young master is no longer obsessed with someone or something as in the past, but becomes more rational and sober. This stems from the plot in the novel Eight Dragons. Duan Yu, the silly young master, is infatuated with Wang Yuyan. He did everything for her, but in the end he found that the person he loved was not worth it, so he decided to give up. This plot is used by netizens to compare some people's love stories and express a kind of reluctance and letting go of love.
