It was always boring to watch your boyfriend study, lying on his bed or in the library alone with him looking at a book as if it was all there was to his life was boring, sure, Remus was cute when he read and when he did anything in general, but you needed stimulation, something more than just watching him read in a comforting way.
Remus had his own study group, you knew that well, Professor Lupin, as the marauders liked to call him was good at his job of teaching, so good that the younger students would come up to him to talk to him and he would gladly answer back.
There was nothing unusual until that little boy came along who looked at Remus with lovesick puppy dog eyes, you didn't even know his name, but he was so . . . Irritating, he forced you to stay close to Remus when he was studying to just mark territory as if the two of you didn't have a secret relationship, Remus noticed, he wasn't an idiot, he knew how you looked at that boy, but he wouldn't say it out loud, it would irritate you
"There’s something wrong?"
Remus asked, he recognized your jealousy but didn't want to show it unless you wanted to.
