My Mute Mate

Do you believe vampires truly exist?
Hikari Dragneel a vampire who lives off blood goes to a normal school however no one knows his secret not even his friends although most of his friend group are in the same situation as him.
Manami Dreyar a relatively normal high school girl except she can't talk other than that Manami is a normal girl however due to her disability the poor girl is often picked on by others.
what will happen when these two worlds collide one fateful day? what if Manami were Hikari's mate? what length's is Hikari willing to go to keep his mate safe and away from other vampires? will he accept Manami Dreyar as his mate?
