The hide-and-seek song is healing and touching.

Astro's debut song, Hide and Seek, is a song that exudes a fresh charm from the moment you hear it. The refreshing guitar sound and bright rhythm combine to make you feel like you're under the summer sun the moment you hear it. The lyrics capture the excitement and pure thrill of first love, so a smile comes to your face and your heart feels warm as you listen. The members' vocals are still young, but they are powerful and refreshing to the ears, and the melody that repeats in the chorus especially gets stuck in your head, making you sing along right away. When you listen to it, scenes from your first love naturally come to mind, making you reminisce. If you even watch the stage video, the members' bright and fresh expressions fit the song perfectly. It's the perfect song to listen to when you start your day in the morning or when you want to brighten your mood.
