The true heir of the Stanley family was buried alive by a parasitic imposter. In his final, agonizing breath, he made a pact with a demon to reclaim his life. Now, inhabited by a dark entity, the 'boy' storms the family banquet to expose three years of abuse and indifference. He doesn't want their late-arriving empathy or their wealth—he wants a blood debt. As the imposter’s mask slips and the family begs for forgiveness, the demon ensures that justice isn't just served; it’s carved out of their legacy.
