Lin Wei's youth hides a "nightmare" named Lu Shiyan. Living in the care of others at the age of five, he was the chosen one with a mean and venomous tongue. He called her a "bumpkin" and "idiot", tore up her first love letter, and used the sharpest words to drive her away. Five years later, her grandmother passed away, and she dug out a diary with rust buttons among her old things. The strong handwriting contained a tenderness that she had never understood - he scolded her for being stupid, but secretly left a note; he mocked her skirt, but sent new clothes anonymously; he stopped her from falling in love early, just to protect her from being let down. It turns out that the "hurts" in those years were all due to his clumsy guardianship; those duplicitous and mean words were all his well-intentioned fear of her dependence and hope for her growth. When she held the diary and stood at the door of his house, was the light in the eyes of the man who had been waiting for her for five years still on for her? Time has not passed, and the affection has not changed. It turns out that happiness is never far away, but in the arms that she has misunderstood for many years.
