He shook his head. "No, I don't despise it." Even if he did, watching Remus' reaction would make up for that. "You're adorable with decorations around. You look about ten when you look at the tree. The possibility of making fun of you makes up for any negative feelings I might have."
Regulus nodded, and went to the trolley to get the cider. Of course, when he turned around to give the glass to Remus, he was more interested in watching his lover, who really looked like a child. "You really enjoy this."
