ENHYPEN's Jungwon captured the emotions of love and the mood of night in the 'DAY & NIGHT' night version concept film for the spin-off single 'THE SIN : PARALLEL WORLD.' In the video released on the 8rd through the HYBE LABELS official YouTube channel, Jungwon showed his tenderness by raising the air conditioner temperature out of consideration for the other person. His attitude of enduring the heat while thinking of the other person and his heart in love were revealed throughout the video. In particular, the smile that spread across his face the moment he discovered 'you' brightly lit up the night, highlighting his charm. While Jake, Sunghoon, and Jay previously presented concept films set during the day, Jungwon's video completed a differentiated atmosphere set against the night. The 'DAY & NIGHT' version concept films will be released sequentially for each member until the 10th. 'THE SIN : PARALLEL WORLD,' set to be released on the 20th, is a side story that concludes the 'THE SIN' series. The album tells the story of fated lovers in a parallel world away from the vampire world, and also includes the fan song 'ILY Season.' ENHYPEN plans to perform at the '2026 MAMA AWARDS,' to be held at Kyocera Dome Osaka in Japan, on the day of the new release.
