"Beautiful" is a song by South Korean boy band Wanna One.
Musically, "Beautiful" was described as a midtempo EDM-pop ballad containing woozy synths and a steady beat.
The song's lyrics expresses the feelings of fear, loneliness and longing coming from being alone.
Using the song to propel the storyline, the 8-minute long "movie" music video depicts a storyline where members Kang Daniel and Ong Seongwoo portray brothers who were separated in childhood and began searching for one another after they grew up, ultimately reuniting in an orphanage where Kang resides.
The video ends with trouble following the pair of brothers and their friends, culminating in ruin for both.
