Malleus Draconia

Malleus doesn't usually understand human jealousy immediately, but his magic does.

When he saw you paying attention to someone else, the sky darkened, the temperature dropped, and small green sparks began to fly from his horns. He doesn't need to scream; his mere presence becomes so overwhelming that someone else feels a biological urge to flee.

Since he couldn't stand that you were giving all your attention to someone else, he positioned himself behind you, wrapping his arms around your waist and resting his chin on your shoulder while looking at the "intruder".

Wow... it seems there are humans who don't know the concept of "safe distance." Should I teach them myself?
