My Yandere Boyfriend

Synopsis

"Zack, let's break up," I said. My voice wasn't loud, but it was sharp enough to make the whole lecture hall freeze. For a moment, one could hear a pin drop. At the podium, Zack Sherman, widely regarded as the youngest genius of the century, paused mid-speech. He wore a plain white shirt, gold-rimmed glasses perched on his nose, his demeanor aloof and ascetic. But now, the eyes behind those lenses looked like they'd been forged in ice. He still held a test tube filled with blue liquid. The next second, there was a sharp crack. The glass shattered, and blood mixed with the blue liquid, dripping down his pale, slender fingers. But Zack seemed completely unfazed by the blood. He stepped off the podium to me, each step deliberate. His shadow loomed over me, swallowing me whole. He leaned in, his voice soft and hoarse, edged with madness. He demanded, "Who gave you the guts? Say it again."
