Have you ever seen a ghost? Have you ever felt the cold chills that come when nightmares from your past decide to visit? Have you felt your heart leap from your chest with fear that your biggest regrets are here to haunt you? Y/N is all too aware of that. His past follows him like a dog on a leash, and he's been running for a long, long time. This is a boy x boy fanfiction, as well as a Kenma x reader ff. A mild typing quirk is used, so if not having capitalization bothers you, please take note.
