"She is entirely too aware of what she's doing." "It blows my mind." "She's quite the killer queen." Y/n Deacon is John Deacon's little sister, and you meet the band at the same time your older brother does. But when your older brother's band mate catches you interest, will the forbidden love shine through? (I'm aware that John has a sister in real life, but he doesn't here. Also, Brian never meets Christina or Anita)
