In spite of your doubts about a potential sucky life, you know that Kelsey had made the last change to you - which means it's unlikely you chose to change your life for the better. Even if you did, you can always change the awareness again later. Taking a breath, you click "User and Target".
Instantly you are struck with another headache, although this one is far briefer than the other. When it clears, you remember everything - especially the part where you're supposed to be a guy. Of course, it would be hard to argue that point to someone, considering you're currently looking past a pair of large breasts to see the phone. The swooping neck of the tank top would display quite a bit of cleavage to anyone, but from this angle they seem even bigger.
"Hey, uh, Gina...?" You almost jump at the sound of Kelsey's voice, having forgotten for a moment she was there. "Are you okay?"
"Um, yeah," you say distractedly. You just had a close call with almost having your entire identity wiped out, and you need some room to think. Absently, you find yourself generating another sentence.
"Kelsey is worried she offended Gina by using her app."
You blink in surprise. So far, this is the most usable sentence you've generated. There seem to be plenty of options. You could change "her", which refers to you now, and be a man again (although you'd have to use another sentence to change your name back). You could also use "she", referring to Kelsey", to change your new roommate's gender. If you wanted to, you could even change "app" to something mundane so that Kelsey forgets about the app and you just remain roommates. What do you do?
