You are grateful. Really! You were close the starvation if Fukuchi, the leader of the Hunting Dogs, didn't safe you. Not only that, he also recruited you! Apparently you have potential or something, but you didn't really are about that, you were just thankful and immediately agreed. Now, Jouno became your mentor, and that's the point were you staft question things. Like, Jouno doesn't really come of like some hero. On the contrary, he seems sadistic!! You don't know the other hunting dogs yet so you can't really say if this is a individual case or all of them are like Jouno.
You two just came back from a mission where there were a robbery. It's not like the mission failed, it never does, but Jouno's way of doing things is...let's just say, not exactly moral...
