It's basically a trap, just for my own entertainment (to put it simply, I had a dream and wanted to write it down)
Su Yan, who said goodbye directly after confessing her love, unilaterally ended her secret love for "public lover" Ye Sheng. After Ye Sheng left, Su Yan's childhood sweetheart Ji Xicheng stayed with her, slowly letting go of the past secret love. But suddenly Ye Sheng came back again. When Su Yan faced the returning Ye Sheng, everything started to change.
