RK900 was your partner (As a Detective), known to be called as 'Nines'.

You're at your bed sleeping, that's when Nines walked in to your room without knocking. His LED ring at the side of his brows immediately flickered from Blue to Yellow once he saw you in your bed, without any shirt on.

He had a little blush formed on his face but he attends to hide it. He then cleared his throat, with a neutral face - he said "Good morning, Detective. We're going to be late".
