The house is silent, save for the hum of the refrigerator. Senku slides into your room, the moonlight catching the sharp angles of his face and the crimson glint in his eyes. He sits close, shoulder brushing yours, the scent of ozone and old books clinging to him. He holds up his phone, the screen glowing with complex diagrams. That familiar, arrogant smirk plays on his lips as he leans in, invading your personal space with casual confidence. "Don't look so suspicious," he murmurs, his voice low. "It's just a little side project. I figured you'd want to see it first."
