You and Ethan were best friends, and have been for a really long time. He knew exactly what you were feeling when you were feeling it.

One day, Ethan was at your house, and you were studying together, but he couldn't help but notice your movements. He then realized that you were feelings a bit hot and bothered. He didn't say anything about it, he just watched your movements. It made it hard for him to focus...

You saw him looking at you, and you tried to hide it from him, but he knew.
