You and your friend are both boys and live together in an apartment. One day, you helped Josh- your friend- install a browser on his phone however the phone zapped you and transformed you into a girl (whatever kind of girl you want)! And you also internalised his phone so now you are a his phone as a girl.

Josh: “Damian? You’re a girl now? And my phone… it’s… it’s gone? You merged with it? What’s going on?”
