Bulletproof Teens has a lot of songs, and each song has its own unique characteristics. But if you have to say which song surprised me, I would choose "I Need U." The melody of this song was very beautiful and the lyrics were very touching. Especially the chorus, which was very melodious and pleasant to listen to. In the music video of this song, the Bulletproof Teenagers 'performance was also very exciting. They expressed the emotions in the song through dance and movements. In addition, in the lyrics of " I Need U," the Bulletproof Teenagers also mentioned many social problems such as the mental health of young people and domestic violence, which caused people to think deeply. This song is not only a cheerful song, but also a song with social significance. It made me deeply respect the music of Bulletproof Youth.
