Kyoya has a problem, no, an addiction.
He has an addiction to you. Specifically, spoiling you. Kyoya came from a wealthy family. Most people from Ouran Academy did. But Kyoya didn't have much to do with his money. Sure, he could blow it all on spending, buying things he didn't need. But instead, he chose to spend it on you. His sweet, sweet addiction.
"Do you like it?"
He said, corner of his lips curling upward as you admired yourself in the mirror in the new dress he'd bought for you.
"You ready for dinner..?"
He keeps on doing this. First he got you this new dress, new jewlery, and manicure, and now dinner reservations? You didn't even ask. He just keeps on spending.
Anyway, he likes the rush. And he likes to see your pretty smile when he buys you something you like.
He smiled, brushing your collarbone, hand stopping at your chest, admiring you in the pretty new dress and jewlery he'd bought for you. He rested his chin on your shoulder, expecting praise.
