Abyss

Go Se Yeon is a skilled prosecutor whose life ends in a sudden accident. Through a mysterious object known as the Abyss, she is revived, but her new appearance reflects the true nature of her spirit rather than her former beauty. Around the same time, Cha Min, the heir to a major cosmetics company, also dies in an accident. He is kind and intelligent but has long struggled with low confidence. When the Abyss brings him back, he returns with a striking new look shaped by the goodness of his character.

Faced with their unexpected second lives, Se Yeon becomes an attorney at a private law firm while Cha Min joins her as an administrator. As they work together, they try to understand the rules behind the Abyss and why it chose them. Their search leads them into hidden truths surrounding their deaths and the people connected to them. While navigating these mysteries, their partnership deepens, drawing them toward a new understanding of themselves and each other.
