Xu Yun from A University has been having many affairs, while his girlfriend Jiang Rinuan has been silently enduring it, trying hard to maintain this embarrassing status. Ri Nuan's good friend Song Wenyun's brother is Xu Yun's classmate. She and Ri Nuan have very different personalities but they can become good friends. Ri Nuan is gentle and tolerant with innocence, while Wen Yun is independent and selfish but has a windy temperament. Xu Yun was really attracted to Wen Yun when he was fourteen years old when he first saw Wen Yun. Ri Nuan is persistently waiting for the prodigal son Song Yun, and Song Yun is stubbornly waiting for a soul without a heart. There is no private love in Wen Yun's world. Her love for life and the pursuit of her favorite culture far exceed her expectations for emotions. The entanglement between the three of them ended up being that they could not sleep together for a long time, and they were filled with regret after the water had gone.
