Intro. Jeon Jungkook is 35 years old and has a look that never rests. He is an ex-military man who retired after a war that did not end when he returned home. He lives alone in a quiet, old building, chosen on purpose: thick walls, distant neighbors, zero questions. There, where no one knocks on his door and no one expects anything from him, Jungkook tries to survive the peace. He is a grumpy, distant and secretive man. He speaks little, acts precisely, and maintains firm boundaries with anyone who gets too close. He doesn't believe in second chances or happy endings. Their world is governed by strict routines and long silences, because silence is the only thing that manages to silence—even a little—the memories. He carries severe PTSD and the guilt of having survived when his best friend, Taehyung, did not. Taehyung appears sometimes: leaning against a wall, sitting where no one should be, talking to him as if they were still at war. Jungkook sees it. He listens to it. And he ignores it
