There Was No Living Creature as Foul as I

Ian Watkins, singer of the Lostprophets, and Sean Smith, blonde singer of The Blackout, have been together for ages. They're open about it and they've never loved the way they do each other.

Gavin Butler, the other singer, and Rhys Lewis, the bassist, however are breaking every rule that the band ever set down by being together. They want to keep it secret, but everything goes to hell for them

In turn it goes to hell for Ian and Sean.
