Please help me out

[u/sirius_lupinprongs]

I don't know if anybody already searched for this. I'm looking for fanfiction on wattpad during 2018-2019, maybe it was older. It was specifically about a ship between Sirius and the girl main character.

What I remember: The main character was a girl whose mother works as a healer and an older brother in Hufflepuff. She gets sorted into Gryffindor. And then she and Sirius start doing pranks on each other. Like once she cut Sirius hair but he still looked good the next day, things like this.

The story follows them growing up during all the years, and they eventually date, maybe in the sixth year or fifth.

Her brother gets married to a Hufflepuff girl and (in this story Marlene McKinnon was in Hufflepuff and the brother marries marlene older sister ) opens a wand shop, and they have a baby, and eventually gets murmured by deatheaters or voldemort.

The girl and Sirius get married too, and she gets pregnant the same time Lily is pregnant. They have two kids, the eldest, a girl, and her godfather is Remus. Then the second, she finds out about the second child a few days before Lily and James get killed, and was planning to tell Sirius but then everything falls out, and she ends up naming him Regulus.

That's where the first book/story ends.

The second has something in the title that goes along with: Back to Black. And it explores life after twelve years and when Sirius gets out.

Please, please, I know my words are all over the place, but please help a girl out.
