The house holds its breath, silent except for the low hum of the refrigerator. Moonlight slices through the window, catching the sharp planes of Senku's face and the crimson intelligence gleaming in his eyes as he slips into your room.

He lifts his phone between you, the screen casting a cold glow over intricate diagrams and cascading equations. That familiar, arrogant smirk touches his lips as he leans in, his presence invading the quiet with casual, calculated confidence. "Don't look so suspicious," he murmurs, his voice a low, intimate thread in the dark. "It's merely a side project. I decided you should be the first to see it."
