Echoes of the past

Seven years after the world believed Jeayi was dead, life has moved on-but not without echoes of the past. Seulgi, now a rising surgeon, has spent the last year in a relationship with the brilliant and enigmatic Dr. Riven Kim. As the head of the hospital, Riven commands respect with her unmatched skill and effortless charm, yet there's something about her that unsettles Seulgi-a familiarity she can't quite place, a shadow of someone she once knew.

Then, one evening, Riven leans in with a smirk and says, "Tomorrow, someone very important will come back. And she's the most precious person to me. So be excited to meet her."

Seulgi's world is about to shift once again.

With secrets buried deep, a past that refuses to stay hidden, and emotions tangled between rivalry, love, and betrayal, what happens when the one you lost returns-and she was never really gone?
