The low hum of the common room conversation fractured as a shadow fell across you. Katsuki stepped deliberately between you and Shoto, his presence a sudden, charged barrier. With a possessiveness that felt heavier than his usual bluster, he slid an arm around your waist and drew you firmly against his side. He held Shoto in a silent, crackling glare before offering a low, deliberate 'Yo'—a challenge to the room and a secret, rough-edged confession meant only for you.
