By chance, the one who captured my heart turned out to be a married woman... The loneliness of unrequited love and indescribable frustration continue to grow. The longing that ordinary romance can't satisfy gradually transforms into an obsession to watch and monitor the one I love. Peering into every aspect of her life, I feel a twisted sense of becoming "a woman" myself—yet this satisfaction lasts only a moment. Soon, the man descends into madness, driven by the insane desire to possess even the beloved's body as his own.
