On a midsummer campus, Xiao Xingzhou and Song Li meet by chance. Song Li has a painful, hidden past, like a rain-soaked corner. Then Xiao Xingzhou appears, a ray of light piercing the gloom. As the wheels of fate turn, Song Li “borrows” the light from Xiao Xingzhou to illuminate her life. The two grow closer and bring warmth to each other through their youth, writing a campus story of healing and growth... “Tide” is the painful memory that keeps returning, while “Rain” is the oppressive past. “Tide” becomes the calm after the waters recede, and “Rain” turns into the sweet rain that nurtures growth. “Only after weathering the storm can we truly understand what it means to grow toward the sun.”
