When Sky Wongravee - a bright, charming paramedic with a soft heart and sharp instincts - crosses paths with Nani Hirunkit Changkham, the cold heir of a corporate empire and underground dynasty, their worlds collide in ways neither can walk away from. Sky doesn't know his face is a mirror of the man Nani lost - a man Nani never dared to love until it was too late. Haunted by guilt, power, and the shadow of betrayal, Nani tries to keep Sky out of his life... and fails. But the deeper Sky is drawn into Nani's world, the clearer the danger becomes - because to protect him, Nani must confront the ghost of the past, the enemy in the present, and a slow-burning connection that threatens to unravel everything he's built. A slow-burn, enemies-to-lovers tale of grief, power, and two souls bound by fate and fractured memory.

"In 1900s, Saint and Shin's forbidden love ended in tragedy-one fell, the other followed, bound by red threads and broken promises... In the present, Sky remembers everything. Nani remembers nothing... yet. As reality blurs and memories bleed through, love turns into obsession, and fate demands a price. Will they heal-or be torn apart all over again?"
