The protagonists, Ji Fanxing and Shen Zhiyi, have been very good friends since they were childhood sweethearts. However, as they grow older, the two people who used to play well together become more and more refined and handsome and outstanding. Ji Fanxing, who is standing next to him, is inevitably drawn out for comparison.
The growing gap makes Ji Fanxing want to stay away from Shen Zhiyi, but the further away he is, the closer Shen Zhiyi gets. Shen Zhiyi, who is indifferent to everyone, is only gentle to Ji Fanxing.
Realizing Shen Zhiyi's tolerance for him, Ji Fanxing became more and more unscrupulous.
Once, he ordered Shen Zhiyi to send a love letter to the girl he liked, Xu Nian'an, but Shen Zhiyi was confessed instead. His mixed emotions of shock and anger made him ready to scold Shen Zhiyi, but maybe God couldn't stand it anymore. He was knocked to the ground by a basketball kicked from nowhere. At the last moment of his unconsciousness, he watched Shen Zhiyi running towards him eagerly.
When he woke up again, Ji Fanxing found himself lying on the hospital bed, and learned that he had actually married Shen Zhiyi, and that he had become the vicious male partner who broke up Shen Zhiyi and Xu Nian'an.
Ji Fanxing: "Is this retribution?"
