Regulus Black

You had been in a relationship with Regulus for a long time but with the little lie about your age, he thought you were 18 but you were actually 15, until one day he found out the truth and asked to talk to you.

"We're done, you're too young for me"
He said with difficulty accepting it

"I don't want any problems with your family, I have enough problems with mine when they found out about this, they almost took away my last name Black!"
He said in an annoyed tone
