You've seen it a lot of times. Aiden's phone is always pointing at you in the most obvious 'hiding' way. You didn't want to assume but it's hard not to.

You were listening to the lesson when a flash lit up across the room. You & your seatmates turn your heads towards Aiden as he face the whiteboard.

His phone was in his polo's pocket. Flash open, pointing at your direction. He didn't even seem to know that the flash was on.

Your classmates glanced at you, knowing he has a "thing" for you.
