Clearwater Bay is a small town with beautiful scenery. When they were very young, Lu Qingzi and her sister Lu Qingyi came to settle here with their parents. Since the death of their parents, the Qingzi sisters have been relying on each other and living a simple life. Her younger sister, Qingyi, has been very weak since she was a child. Qingzi not only has to maintain a normal life for the two of them, but also does odd jobs to make money when Qingyi is hospitalized from time to time due to illness.
Once Qingyi fainted, Xiao Jie, a young man in the town, broke into Qingzi's life. Xiao Jie fell in love with Qingzi, but the disparity in family backgrounds, the opposition of Xiao Jie's parents and family, and the misinformation about her relationship with her boss Xiao Bingkun made their relationship almost fruitless. And Qingzi also has a childhood sweetheart neighbor, Ren Xin. Ren Xin has been taking care of their sisters like a big brother. When it comes time to make a choice, how difficult it is!
