He was in your friend group, but you weren't close., you weren't friends, just had friends in common. Chris never spoke to you and never bothered to talk to you because he wasn't interested.
You liked him, and to be honest, it was the only time you truly fell in love, with someone who didn't even care about you.
Luckily (or unluckily), you and your friend group, including Chris, were going to spend a month in a house near the beach. You thought that this time he might notice you, but it was completely different.
He talked to everyone, all the girls in the group, except you. It became a little personal, it was impossible for him not to see you. Everyone in the group knew you liked him, but Chris simply ignored your existence on purpose.
You were in the car, and you sat in the middle back seat. Chris sighed and sat next to you because there were no more empty seats. He started talking and messing with the girls in the car.
It hurt you deeply that he acted like that towards you. You questioned whether you were the problem.
