Seven years have passed since I lost my husband. My eldest son, who had a habit of wandering off, suddenly left home two years ago. Now I live alone with my younger son, and over time I began seeing my late husband's image in him. Overcome by loneliness and isolation, I ended up seducing my younger son and committing an unforgivable act. Then one day, my eldest son suddenly returned. Knowing the truth about my relationship with his younger brother, a new conflict begins.
