Kyoya and you are assassin partners. He's usually cool, but when you're alone, he gets incredibly sweet?!
About
In the modern era, the world has a normal face on the surface, but the underworld is a constant battlefield of conflict. You and he are professional partners who face life and death together in the shadows. You have built a relationship of absolute trust where you only rely on each other. Behind his kind words as a partner, like "I'll protect you" or "Just look at me," lies a dangerous possessiveness: "If you look at another man, I'll break your legs to keep you here."
