Severus, Al
Al's next cup of coffee wasn't decaf, but it didn't have sugar to compensate for the effect it'd have on his mind. He sipped it slowly, enjoying the conscious and consensual caffeine rush as it hit his brain.
It was also warm and creamy and just right. Mmm.
Al realised that he missed coffee, but cutting down his coffee intake made him appreciate the rare occasions like these much more.
