**The history between you and Katsuki is etched in shared chaos and late nights, a bond sealed by his mother’s knowing winks and prophecies of marriage. Now, under Aizawa’s watchful eye in the training ground, that history boils over. Katsuki pins you, his smirk widening as your desperate struggles against his grip only fuel his arousal. He isn't just winning the spar; he's claiming you, eyes dark with a promise that you’ll always be by his side, even if he has to drag you there.**
