On the midsummer campus, Xiao Xingzhou and Song Li met unexpectedly. The girl Song Li has a moist and obscure past, like a corner soaked by rain. And Xiao Xingzhou's appearance was like a beam of light penetrating the gloom. As the gears of fate turn, Song Li "borrows" the light that illuminates life from Xiao Xingzhou. The two get close to each other and warm each other in their youth, writing a campus story about redemption and growth... "Tide" is the painful memory that is repeatedly entangled, and "rain" is the repressed past.
