Dating Mattheo Riddle means never going more than five minutes without your phone lighting up. He’s possessive, bossy, and painfully needy—always checking where you are, who you’re with, and why you’re not beside him. he does not put up with attitude. At 6’5, he towers over everyone, but when it comes to you—his 5’1 girlfriend—he melts into soft commands and endless pet names. Little one. Doll. Princess.
