Songfacts®:

• Released as the lead single from Ateez's In Your Fantasy Edition of their 12th EP, Golden Hour: Part.3, "In Your Fantasy" trades in the K-Pop boyband's high-energy bombast for something far more slinky and suggestive.
  
  The song rides a seductive electronic pop groove that sounds like it was lifted from Timbaland's hard drive circa 2006, with some modern R&B and funk flourishes thrown in for good measure. There's a definite SexyBack flavor here, only less brash and more alluring.
• Lyrically, "In Your Fantasy" is an invitation to surrender inhibition. The chorus features a recurring motif - "Lucifer, devil in disguise" - that casts the Ateez members as seductive tempters, dangling the possibility of ecstasy but denying transcendence. As they put it:
  
  Heaven is in my stare, but I ain't gonna take you there
  
  It's not salvation they're offering; it's something far more debauched.
• True to Ateez's ethos, the song wasn't simply handed to them fully formed. Hongjoong and Mingi, the group's resident creative anchors, are both credited as lyricists. They worked alongside an experienced crew of producers and writers, including Eden, Maddox, Peperoni, OLIV, and Alexander Karlsson - names well-known in Ateez's world and beyond.
• "In Your Fantasy" became Ateez' second song to enter the Billboard Hot 100, following the fizzy success of "Lemon Drop." Available in both Korean and English versions, the track was clearly built with global ears in mind; and judging by the chart response, those ears were listening.
• Ateez told Genius that part of their appeal comes from building a "fantasy world" on stage, one that fans often describe as feeling like being transported into a dream. The group leans into this idea in "In Your Fantasy" where they frame themselves almost like a force you can't escape, telling listeners to stop resisting and "just come aboard with Ateez." Even the choreography - full of arm-raising movements meant to suggest liberation - was designed to amplify that feeling of surrendering to their universe.
• Ateez enjoy layering their lyrics with hidden or double meanings. One member noted that while some "In Your Fantasy" lines might sound playful or even risqué ("come take a bite"), they're deliberately written to leave room for interpretation. Fans who pick up on these subtleties get a little extra thrill from decoding the band's wordplay.
