Jiang Yi poured everything into supporting his small family, but after his wife achieved career success, she insisted on a divorce. That night, he risked his life to rescue a girl in danger, only to be hospitalized with serious injuries. In the hospital room, the middle-aged woman who caused the accident stared at him for a long time—this face looked extremely like her younger brother's in his youth. Vaguely sensing a connection, she left her contact information under the pretext of taking responsibility and secretly investigated, eventually unearthing Jiang Yi's long-lost biological father. The return of familial affection allowed Jiang Yi, who was at rock bottom, to stand back up. He took firm, grounded steps to start anew, using responsibility to protect everyone around him. The end of a marriage is not the end; the appearance of a biological father ushers in a new birth.
