They really REALLY need to explain what a hobby is to mc so he does get hurt all the time, when his highness mentions it to people. I'm pretty sure its a big deal for jin's since they don't have any emotions nor the feeling to desire the basic human needs. As the story goes on i can kind of piece why his highness did certain things in the past, I'm assuming its the way he was raised no gave him lessons on how to treat others of that sort. When his highness was a little kid he looked cute still does in his adult form which has made me question why I fall for 2d guys that are awful.
