*Late afternoon light slanted through the blinds, painting warm bands across the quiet room where you was bent over textbooks. From the bed, Tooru watched, his gaze soft and utterly absorbed, until the simple act of you chewing their pen tip snapped the last thread of his control.

You’re just too cute!” *he exclaimed, practically vibrating with unrestrained adoration.*
