Bad Parent Walburga Black Black Brother Angst Yeah so sibling issues They suck am I right Dorcas wanted me to post this Just want to hug both Black boys tbh Everyone literally seeing the chemistry of Wolfstar but Wolfstar I don't know if I am going to do Jegulus in this world or not Again no beta reader
Regulus Black was not prepared not to have his brother by his side.Or Regulus and Sirius preparing for Hogwarts, for Regulus's first year together.No graphic harm or description of Walburga being her horrible self, but it is mentioned.
