Three years after their dramatic breakup, Song Qingwu returned to Jinghai, but that night she ran into her ex-boyfriend whom she kicked three years ago - Zong Yu. When they broke up, he said, "Song Qingwu, you are like rain and a lake, difficult to cross." Song Qingwu thought that with his arrogant and proud character, he would never look back. But she didn't expect that three years later, he would pester her repeatedly and even chase her to the door of her house. "Song Qingwu, no matter who you fall in love with or who you are with, you must share half of yourself with me." Thousands of rivers and mountains have passed by over the years, but when I meet you, I am still completely defeated.
