Su Hang, an interior designer, adopted the landlord's child who died unexpectedly while studying abroad and regarded him as his own. The names of the landlords are Song Yi and Jiang Xiaoyu. It was because Song Yi's parents looked down on Jiang Xiaoyu that they fled abroad to get married. Later, she died in a traffic accident. Song Yi's mother was looking for her granddaughter, but Song Yi's family had never met Jiang Xiaoyu, so they thought Su Hang was Jiang Xiaoyu. Song Qixi was Song Yi's younger brother. They found Su Hang through detectives and thought she was Jiang Xiaoyu, so they approached Su Hang and fell in love with Su Hang after a series of things happened.
