The song "Decalcomania" by Jung Kook is about a person's admiration for someone they see on the screen. The person is perfect in their eyes and is good at everything, making them feel like they have never been like that. However, the person wonders if the object of their admiration even sees them or knows who they are. They long to be like this person and want to understand them better. The lyrics also talk about how the person wants to escape from the pressure of constantly trying to achieve big things in their own life. They want to be like the person they admire who seems to effortlessly succeed at everything. The person wants to be like a decalcomania, which is an image that can be transferred from one surface to another. In essence, they want to become this person's reflection and be alongside them. Overall, "Decalcomania" is a tale about the pursuit of perfection and the desire to be like someone who seems to embody that ideal. It shows how social media and the internet can create fantasies and ideals that are impossible to attain, leading people to feel inadequate.
