Lost and Found: The MV captures the members in various moments that evoke a cinematic music drama: from the band practicing together, to Gaon and Jooyeon running somewhere, O.de and Jun Han, Jungsu deep in thought, and Gun Il observing something with a focused gaze. Each scene reflects a unique facet of youth. The song is about someone waiting endlessly for love that never comes back. They feel lost, tired, and hopeless, wishing to be noticed or let go completely. It captures the pain of waiting, the loneliness of being forgotten, and the desire to be found again.
