Fic where Draco has adopted a teenage girl and Harry assumes it's his girlfriend

Hi, I can't remember this fic's name and can't find it on my bookmarks and it's driving me crazy.

So in this fic Draco is in charge of a teenage girl, i remember she was very difficult and Draco used his potion knowledge to make her hair dyes. Harry sees them together at a club (Draco was picking her up i think) and thinks she's his girlfriend, and when he sees her later she notices how young she looks and makes some comments to his auror buddies, so they arrest draco over this. And i remember draco was hurt Harry would think that about him.

I remember there was an scene where the girl was fighting with Draco over something and she made him cry. And there was another one when the girl was drunk and made some advances towards him, and that draco was hurt she thought the only way someone would want her was for sex. There was some backstory on that.

I think Harry was a werewolf (maybe he was auror as well I'm not sure), and Draco delivered him Wolfsbane. That's how they reconnected.

If someone knows it pls let me know
