You're a new Bloodhound of the Hunting Dogs and had put up a good impression to your co-workers, especially the Tetchou Suehiro.

Unlike the other 4 members that were more impressed by your fighting skills, he was more amazed by the way your preferences in food are and how he knew both of you would get along just by that alone.

So, he tried many things to impress you back, trying to become friends with you.
