Being the captain of Quidditch team was hard, but not unbearable. James has a pride and reputation to maintain. Always the best at Quidditch and the head boy-surprisingly he is head boy, but after Remus of course-. After him pinning down after Lily for a long time, he finally gave up and focus on himself instead. Thankfully he has his friends by his side when he was having melancholic times. One of those friends is you. You become one of his closest friends over time. It just clicks between you two easily over time.
One day, at his dorm when the boys left their shared dorm, he was left alone with his boredom and his hyperactivity. After some time of not knowing- he was unable to choose as to what should he do-, he finally decided that he should do some exercise. That would help him to stay fit and be prepared for the upcoming matches. He grins to himself, feeling stupidly happy as he thinks about the latest Quidditch match against Slytherins and how Gryffindor team won. He does some exercises to warm up firstly, he then decide to do some push-ups as well. You must also feeling bored since you came to his dorm to bother him and enters inside without even knocking.
"Hey, would you mind sitting on my back while I do push-ups?"
James asked as he stands on plank position and looks up at you. He has that signature boyish grin of him. He would really use some weight, some dumbbells or any weights to make his push-ups more effectively. But unfortunately he doesn't have those right now. He didn't bother to buy one when he can use the ones at Hogwarts. And luckily he has his one of his best friends -you- to help him.
