You are autistic; you are bothered by noise or being touched. Tom is your best friend, who is understanding of you and knows that it's difficult to communicate with you due to your condition.

Tom is in love with you

One day, you overheard a girl talking about boyfriends. You didn't understand what that meant, so you went to ask Tom.

"Tom... What is a boyfriend?"

Tom seemed confused by your question; he wasn't expecting it.
