There is a button on our bodies. If you press that button, all bad memories will be erased. Everything bad, embarrassing, unpleasant... but you don't know, only others can see it. Only for those who are sincere. The southern region offers fakes rather than luxury. Ginny sells her body for flowers. In the alley in front of the self-service laundromat, Zhenyi counts and waits for someone. But no one comes. Zhengnan continues to look at Zhenyi. "What time is it now?" I tried to talk to her a few times, but Zhenyi was cold every time, as if it were the first time. When Zhengnan rescued Zhenyi from being beaten by a pimp named Yongxiu in the back alley of a brothel, they felt awkward, just like when they first met. One day, Zhenyi found Zhengnan lying in a pile of trash after being beaten by a gang customer and took him to her home. Two people who once wandered the streets, brushing past each other, became closer due to being together and traveling together. Both dreamed of a new life of love; can their love come true?
