Songfacts®:

• This feel-good song is a solo track recorded by Jungkook for BTS' Love Yourself: Answer album. It finds him singing in both Korean and English about the heady euphoria of new love.
• The song started as a personal solo work by Michigan-based singer-songwriter Candace Nicole Sosa with the title "Killing Time." Needing some advice on how to improve her tune, she contacted frequent BTS and Chainsmokers collaborator Jordan "DJ Swivel" Young to ask him about his rates.
  
  "I remember e-mailing him at 3 a.m. one night and sending a sample of Killing Time, not thinking he would respond," she recalled to South China Morning Post. "But when he called me a couple days later while I was working at Starbucks, I was shocked that a big music producer would be interested in my songs."
• DJ Swivel told Sosa he wanted to work with her on "Killing Time" and turn it into a track that an established artist might pick up. Together with songwriters RM (of BTM), Adora, Melanie Joy Fontana, Supreme Boi and Hitman Bang (BigHit Music CEO), they transformed it into "Euphoria."
  
  "There was a lot of back-and-forth between the Korean writers and ourselves on the direction of the song, yet we were given a lot of flexibility at the same time," said Sosa of the collaborative songwriting arrangement.
• RM wrote the bridge and part of the pre-chorus. He explained on BTS' V Live site that he added the "When I'm with you I'm in utopia" line because "utopia" and "euphoria" sound similar. Also, he changed the original Korean line "I hear the faraway waves" to "I hear the faraway ocean."
  
  RM said: "There is an animation film called The Ocean Waves. It's a very romantic animation. I thought the vibe of the animation and the emotions of the song fit together. 'I hear the ocean' is something you learn at school. Synaesthetic imagery. So I changed it to 'I hear the ocean' and I'm happy with the result."
• Candace Nicole Sosa plays the guitar on the track; DJ Swivel performs all the other instruments.
• Swivel also had a hand in the Answer: Love Myself title song and in another track, "I'm Fine."
• The song plays during the season 1 finale of HBO's Euphoria TV series.
