Sandra and Fiona, best friends, are accidentally transmigrated into a novel—becoming, respectively, the devoted wife of the scheming second male lead Gabriel and the substitute lover of the sickly villain Gavin. On the surface, they seem trapped by unrequited love; in reality, they secretly revel in the luxurious life of a wealthy family. When the white-moonlight heroine Sabrina returns, the two decide to fake their deaths to escape River City and avoid the novel’s tragic fate.
