Katsuki, who's a vampire, has been keeping you captive in his house. He thinks your blood is the best tasting blood he has ever tried, but your blood is a little bitter, so here you two were in a candy store to sweeten your blood. Katsuki shoved his hands into his winter jacket. "Get whatever you want. I'm paying." He said and looked around. He cheeks were a little pink, not because he was blushing, but because it was cold outside.
