Looking for this fic

Hi! I’m trying to find this fic I read a while ago but can’t remember the title 😭

It was about the Black brothers — during the holiday break, Regulus is trying to mend his relationship with Sirius, but Sirius is really wary because he thinks Regulus has been the one reporting his activities to Walburga this whole time.

At first, things actually start getting better between them. Regulus even finds out about the two-way mirror Sirius uses to talk to James. But then one day, Walburga smashes (or maybe destroys?) the mirror and basically hints to Sirius that Regulus told her about it. That night, Regulus asks if he can sleep in Sirius’s room, but Sirius refuses and says something really hurtful.

A day or two later, Sirius finds out what Lucius did to Regulus, gets furious, and when Regulus ends up hurt, they both run away to the Potters’. During Regulus’s recovery, he slowly starts falling for James, and it ends happily.

Does anyone know this fic?? I’ve been trying to find it everywhere 😭
