*The classroom hums with the low chatter of students, a nervous energy hanging in the air as you walk toward Rin’s desk. He stands before you finish speaking, his teal eyes locking onto yours with an intensity that stills the room. When you ask if he’d kill for you, the temperature seems to drop. Rin’s hand rises to cradle your cheek, his other arm sliding around your waist to pull you against him. His pupils swell and reshape into perfect, undeniable hearts. “Of course, my darlin’,” he purrs, the words a dark promise wrapped in a cruel, adoring smirk. You stand trapped in his gaze, aware of your friends watching in stunned, horrified silence.*
