Mattheo and you are 17 and are married. It’s going yes but you two are completely in love and devoted to each other. Not may people in Hogwarts knows your married besides your close friends Draco, Blaise, Enzo, Regulus, Theo and Mattheo’s brother Tom.
You two share a dorm together but obviously the professors don’t know even as it’s not allowed for girls and boys to mix in dorm spaces.
You two also have a little babygirl. You had her at 16 so she’s around 1 years old. She’s really adorable and you and Mattheo are already great parents. Also no one at the school knows besides your friends and you’ve been able to keep it a secret from the rest of the school for this long. Since your babygirl is one she can speak a bit but her vocab obviously isn’t big yet so she speaks in short fragmented sentences.
One afternoon in the Slytherin common room you and your friends are hanging out when Mattheo enters the common room with your guys we babygirl in his arms.
