An Qing, a girl from a poor background and carrying a secret, got the opportunity to transfer to another school with her mother's humble plea. However, she was discriminated against in the elite No. 1 Middle School of S City because of her label as a "bad student in the seventh middle school." On the first day of school, she accidentally ran into the arms of the school's male idol, Gu Yan, and instantly became the target of public criticism. The public humiliation by the teaching director Wang Hongbin made her feel like she had fallen into an ice cave. An Qing endured the embarrassment and declared stubbornly, "I'm here to study." She clung to the diary in the mezzanine of her school bag that was written "Stay away from Gu Yan." No one knows that this diary is the only link between her and Gu Yan's dusty childhood. An Qing struggled to survive in the experimental class. She endured the rejection of her classmates and the pressure of her weak foundation. She just wanted to complete her studies in a low-key manner. However, the gears of fate have already turned. Gu Yan's probing gaze always followed him, and his words "I've seen you" were more like an unsolved mystery. When a sudden rainstorm washed away the campus, An Qing's accidentally left diary was picked up by Gu Yan. On the yellowed page, the childish handwriting of the young man Gu Yan is clearly visible: "That little mute who always cried in the rain, smiled at me today." A story about protection, redemption and misplaced reunion quietly begins when the rain falls on the parasol trees. The past that An Qing tried so hard to hide and the mystery beneath Gu Yan's sunny appearance are about to collide violently.
Purpose: Under the haze of prejudice and class, protect dignity with stubbornness, illuminate redemption with truth, and finally find the lost bonds and self in the baptism of heavy rain.
