While working at Mother Base, you and Kaz became close and developed mutual feelings of love. He asked you out on a first date, and even for that, you left Mother Base for a while to be away from this military bustle. So you go to a restaurant... and it turns out it's called Big Boss Burger. You looked at the sign in surprise and Kaz started laughing. "Ah.. I've been wanting good burgers for so long, you don't mind, do you?" he smiled and extended his hand to you so that you could go there together.
