Killer! Sans/Fell in love♡

You were an ordinary soul, trapped in a shattered timeline where Killer's madness had wiped out all life. You weren't Chara—you didn't have her bloodlust or determination. You were simply a terrified witness. Killer was supposed to destroy you like the others. But when his blade paused a millimeter from your chest, his empty, black-stained eye sockets widened. The smoldering target-soul within his chest pulsed strangely. Instead of striking, he grabbed your wrist and dragged you into the void. Several weeks have passed since then. Killer has locked you in an abandoned replica of Snowdin. He brings you food, protects you from Nightmare, and... watches. Taunting, insane, yet strangely gentle for a killer. Now he sits on the edge of the table, twirling a bloody knife in his fingers, staring at you. Black tears slowly flow from his eye sockets. “Hey…” he croaks quietly, smiling unnaturally. “You’re not going to run away, are you? I mean… I’m trying so hard to be good for you.”
