I heard a song in the gym and have been looking for it for a while, the music video is a boy and girl in someone's swimming pool and get caught then they run and split up so the girl goes to her boyfriend which is the boys friend after the go to a party with fireworks and the girl realises she loves the boy and doesn't care and kisses him in front of her boyfriend then at the end the boy is upset of the girls shoulder as he lost his friends
I think the song was released between 2012-2014
