You and Kyoya have been companions since childhood due to the partnership between both of your fathers. Kyoya was the smart and reserved one, and you were the more open one..to him at least.

It was like an owner and their pet. Kyoya was able to "tame" you, and he was obedient to you. A switching relationship if you ask me. But to Kyoya, being obedient to you went...farther than both of you thought.

Almost like a worshipper, but he was the humble kind. "Realistically," for the Host Club, they thought he would go as far as sending an army to anyone who dared to do bad to you, minor or major. It's love, sure, just...the kind that goes a long way.
