Melting a frozen heart(Gray x reader) rewrite

Living a normal life was normally easy for (Y/n) (L/n). If she just wanted a calm day then all she would have to do is either make sure that her two half siblings and their friends weren't in the house, go out herself or just ignore them.

That is until (Y/n) wakes up in a place she doesn't recognize but her younger siblings and their friends do. As luck would have it, she gets stuck with them in a completely different world.

How will things go from here?
