Su Xingluo and Lu Zhinan were childhood sweethearts who grew up across the street. From playing in crotchless pants to sitting side by side in their senior year of high school, this friendship that others envied had already quietly deteriorated in their hearts. During the cicada chirping in the senior year of high school, he took care of her trivial matters in the name of "convenience", and she used "convenience" to cover up the tenderness she had hidden for a long time; in the distance after the college entrance examination, he used the excuse of "passing by" to go to her appointment, and she silently waited for his return.
From the green temptation to the frank rush, from the school uniform to the wedding dress agreement, there is no bloody misunderstanding, only the subtle sweetness - it is the support at the school sports meeting, the panic holding hands on New Year's Eve, the mutual companionship under the postgraduate entrance examination lights, and the promise for the rest of the life deep in the alley.
