In the midsummer of youth at the age of fifteen, there is a two-way misunderstanding that spans ten years.
Shen Yuchu and Fu Huaian, who were in the same class in junior high school, secretly fell in love with each other, but were blinded by their childhood sweethearts.
Shen Yuchu watched Fu Huaian caring for the gentle sister next door and thought it was youthful preference, so he could only quietly put away his ignorant feelings; Fu Huaian watched Shen Yuchu and Zhuma brother closely accompanying each other, and concluded that she already belonged to someone, and hid all his love for her.
An unspoken misunderstanding quietly took root, and the two of them drifted apart and lost all contact.
Shen Yuchu became a gentle and calm doctor in white clothes, and the sweethearts around him always regarded her as his sister; Fu Huaian rose to the top of the business world and took charge of a wealthy family, but the childhood sweethearts around him never had any affection for him.
The reunion of their 25-year-old junior high school classmates was an opportunity for them to reunite after ten years.
Fu Huaian made a special trip to the banquet just to wait for Shen Yuchu, but it happened to be that she was unfortunately absent from the hospital dinner party.
After an accidental encounter, the old misunderstanding was suddenly solved, and the two people suddenly realized that they had been thinking about each other for ten years, and it had always been a one-way misunderstanding and a two-way secret love.
