Liang Ruoqing is a girl who, after being lied to and dumped by her ideal high-school boyfriend Ai Ren, develops love phobia and vows to never fall in love again. However, she meets a handsome doctor Lu Zhehan at her grandfather's hospital. Lu Zhehan seems to be the perfect guy but since she doesn't believe in "perfect" anymore, she thinks that he is too good to be true. Her new journey begins when she tries to show to all of the women that this doctor is not as good as everyone thinks he is, but fate is playing a trick on her. The more she tries to uncover his hidden evil nature, the more she discovers that he may be the right guy to cure her love phobia.

Inspired by a true story, "Second Life" follows a woman determined to swim across Taiwan's Sun Moon Lake before she loses her sight completely. She's joined by a group of visually impaired swimmers, all guided by a once-celebrated coach haunted by his past. As they train together, they battle fear, doubt, and old wounds—transforming pain into strength, and strangers into a family. More than a swim, it becomes a journey of healing, redemption, and proving that even in darkness, the human spirit shines brightest.
