Mile Phakphum is a businessman who is burned out from the grind and takes an 'early' retirement to renovate a 'haunted' mansion. Apo Nattawin is an inhabitant of this mansion called "Heaven's Island", not as a ghost, but as a cat. A businessman and a shapeshifter. One cursed to solitude. One cursed in limbo. They discover friendship turned into a unique love, truths about the curse, and find ways to break the curse. (Businessman x Shapeshifter AU)

In the golden age of the Siamese Kingdom, Khun Mile, a stoic royal guard, serves in silence-his duty to protect the fragile, golden-caged prince Apooraya, known for his radiant smile and untamed spirit. What begins as a silent protection turns into an unspoken yearning. But politics, betrayal, and war pull them apart before their hearts can fully touch. Centuries later, in modern-day Bangkok, rising actor Apo begins dreaming vividly of a man in crimson armor who calls his name like a prayer. Meanwhile, renowned director Mile Phakphum, famous for historical dramas, begins crafting a film about a forgotten love story from the old Siamese court...only to realize the characters match the man in his own dreams. Fate begins to unravel-and stitch again. As past and present blur, the two must uncover the truth of who they were, why they were separated, and whether this lifetime will finally let them finish what once began beneath a silk moon.

Being a college sophomore definitely didn't help Nattawin to realize how important it is to survive. All he did was skipping classes, smoking cigarettes and dogdging questions when people asked about his studies. After the death of his grandmother, his world turned grey and he believed that there's nothing more to look forward to including pursuing his studies. But everything changed when he met Mr. Rome. The big boss of the Romsaithong Empire who suddenly out of nowhere, became Nattawin's black card. But owning a black card also means owing. Well, in this case, only God knows how much Nattawin owed Mr. Rome.
