The song "Nobody Has to Know" by Thomas Headon is about a casual hook-up between two people who are not looking for love, but enjoy each other's company. The two meet on the sofa and start making out. The protagonist admits to breaking up just two days before meeting the other person. They both agree to keep it casual and continue to hook up without any expectations of falling in love. The chorus repeats the phrase "nobody has to know" which suggests that they are keeping their casual hook-up a secret. They want to continue their relationship without anyone else knowing what they are doing. The protagonist mentions that they sneak into each other's houses at night without anyone else knowing. The second verse suggests that they sneak out in a stolen car and narrowly avoid a police car. They end up at the protagonist's house where they have sex. The hook-up seems to be emotionally fulfilling for the protagonist, even though they know it is wrong. They suggest that their arrangement can continue in the future. Overall, the song is about a casual, secretive relationship and the thrill and excitement that comes with it.
