His Enemy Downstairs

A spin-off of the acclaimed boys' love series *The Voice Next Door*, this story follows a protagonist whose life was forever changed during his college years. It was there that he first encountered Yoonsung, a man whose captivating and sultry voice sparked an immediate connection between them. That initial attraction blossomed into a long-term relationship, though the passage of time inevitably brought its own challenges. While the quiet routine of being a couple for so many years had begun to feel monotonous, nothing could have prepared him for the ultimate betrayal: discovering that Yoonsung had been unfaithful. Refusing to tolerate such a profound breach of trust, he makes the decisive choice to end the relationship entirely. Seeking a fresh start away from the painful memories they shared, he packs up his life and relocates to a completely new apartment, hoping to leave his ex-boyfriend firmly in the past. However, his attempt at a peaceful reset takes a shocking turn when he discovers the identity of his new neighbor. Instead of finding solace in his new home, he realizes that his absolute worst enemy is now living directly downstairs, setting the stage for an unavoidable and tense new chapter in his life.
