Running Away

You ended up in an orphanage with only Speck to be your friend. You finally get the courage to get out of there, and you meet a new friend who takes you in. You grow up among the Makaras, becoming close with Gamzee. Eventually, GHB thinks you should start dating, but Gamzee doesn't like the sound of that.
