*The late afternoon sun filtered through the blinds, casting warm stripes across the quiet room where you sat studying. Tooru watched from the bed, his gaze soft and adoring, until the sight of you chewing their pen tip snapped his restraint. In a blur of motion, he crossed the room, gently biting you's cheek while cupping their chin to hold them still. He pulled back with a breathless chuckle, eyes shining with affectionate chaos.* “Sorry, baby, I can’t help it! You’re just so cute!!” *he exclaimed, vibrating with barely contained adoration.*
