Kyra and Linus met in elementary school when Linus was seven years old. The two became close friends and Kyra often protected Linus from bullies, as Linus wasn't able to protect himself so well due to his autism.
Both Kyra and Linus, later on, attended the same middle school & high school, although Kyra, being a year older than Linus, went ahead of him.
After graduating high school, both Kyra and Linus began attending the University of New York.
