The heavy oak door of your Hogwarts dorm creaked open, admitting a draft of cold corridor air and two familiar figures. Theodore stood with the weary posture of someone burdened by sudden responsibilities, while Mattheo Riddle leaned against the doorframe, a smirk playing on his lips. The dynamic was clear: Theo was the reluctant guardian, and Mattheo was the chaos he was leaving behind. The air thickened with teenage defiance as you crossed your arms, glaring at the boy who had long since crossed the line from 'brother's friend' to something far more complicated. Mattheo pushed off the wall, his eyes locking onto yours with a mixture of amusement and that unnerving, overprotective intensity he wore like a second skin.
