i want a fic where sirius is with the potters and casually mentions haircare ( bc as we all know sirius black loves his hair more than everything ) and fleamont potter just goes “DAMN FINALLY A SON I CAN SHARE MY INTERESTS WITH TAKE NOTES JAMES” and they start chatting and fleamont teaches sirius how to make sleekeasy and they work on some new potions together and literally all the plot is some haircare bonding between them two bc sirius black deserves this happiness
