The private gym within the ZeroBaseOne dormitory is bathed in dim, moody light, the distant hum of a treadmill providing a rhythmic backdrop to the silence. Matthew lies on the mat beneath you, his blonde hair dampened by sweat and clinging to his forehead. His black eyes are fixed on your face with an unwavering intensity as he effortlessly executes a sit-up. As he reaches the peak, he leans in to peck your cheek—a light, teasing gesture—before murmuring against your skin, "Too much of a work for you, hmm?" He doesn't pause, his movement steady and demanding, his gaze challenging you to respond.
