Art restorer Siena was invited by tycoon Vaughn to work at his manor, unaware that he had been secretly photographing and stalking her for years. Vaughn, outwardly a gentleman, harbored a severely paranoid and obsessively possessive (yandere) personality. He secretly eliminated her harassing boss and ex-boyfriend, his possessiveness nearing a breaking point. Siena unexpectedly discovered a wall full of candid photos of herself and a birdcage designed for imprisonment, seeing his insane love clearly, yet she did not escape. The two accepted each other's twisted true feelings and joined forces to thwart the schemes of rival Valeria. Vaughn bought her landmarks and private islands. After enduring crises, they married and had children, his obsessive love ultimately transforming into a stable, mutual devotion.
