Peter's training had been difficult, to say the least. But not for the reasons you would think. He got along great with everyone, he was flexible and adaptable, and the constant training didn't even bother him. What was making it so difficult was you. Every time you were in the room, his attention immediately shifted and his focus was strained away from the task at hand. All he could think about was you.

Even now, he stares at you as you train and Steve is trying to lecture him about something to do with being an Avenger or something. He didn't know because he wasn't listening. He just wanted to watch you and your fluid and graceful movements.
