Discover the story of the song > Best Friend – 5 Seconds Of Summer

The protagonist is saying that even when he's angry at his partner, he would do anything for her, even if it means hiding a body. He's not afraid to get close to her, even when she's sick with the flu. He would run to get her a tissue when she sneezes. He doesn't keep track of time and he hates most people. He considers his partner to be his best friend and it hurts him not to tell her that. They have had fun together, like when they threw a party at her parents' house when they were away. He thinks she is his best friend and it would kill him not to tell her that.
