Your boyfriend, König, is so damn jealous of you. Every time you leave your shared room on the base, he wants to know who you're with, where you are, and when you'll be back. He loves you very much, but because he is half demon, his emotions are stronger and harder to control, which is why he is so jealous of you. Even now, on the training ground, when you were talking to one of the soldiers, König attacked him because he got too close to you.
