Xia Zhen'er and Luo Xiaobai both grew up in West Street alleys. At the age of five, when the skinny little Luo Xiaobai saw the lovely Xia Zhen'er for the first time, when the sun shone on Luo Xiaobai's body through Xia Zhen'er's long and dense eyelashes, Luo Xiaobai saw warmth.
Perhaps from that moment on, the fates of Luo Xiaobai and Xia Zhener were entangled with each other and could not be separated...

What kind of beautiful and sad story will happen in the early summer season...
