I was impressed that not only was there a different voice for Girl Version but that it wasn't just a female actor double-roleing like with Kampfer; it was actually a different voice actor.
There's also little bit at the end of each episode where they explore what might have happened if he had chosen a different option. Can you guess what it was for episode 2?
