Singer Gain and 2AM’s Jo Kwon are reuniting for a special duet marking their first musical collaboration in 16 years and bringing back memories of their beloved “Adam Couple” era.
On December 17 at 6 p.m. KST, Gain and Jo Kwon will release a collaborative OST track titled ‘We Fell in Love’ (2025) through major music platforms. The song has been selected as part of the soundtrack for the upcoming film ‘Even If This Love Disappears from the World Tonight,’ adding emotional depth to the movie’s romantic narrative.
A Song That Defined an Era, Reimagined
‘We Fell in Love’ originally gained immense popularity in 2009, when Gain and Jo Kwon performed it during their time on We Got Married Season 2. Their natural chemistry and sincere delivery turned the track into an iconic duet, closely associated with the “Adam Couple,” one of the show’s most beloved pairings.
Now, in 2025, the song has been newly reinterpreted. Rather than simply recreating the past, the updated version promises a more mature emotional tone, reflecting the artists’ growth over the years. Listeners can expect deeper sentiment, refined vocal expression, and a richer harmony shaped by time and experience.
A Winter Duet Filled with Emotion
According to a representative, the song’s strength lies in its storytelling. “The lyrics convey fluttering emotions that naturally resonate with listeners,” the source said. “With more convincing storytelling and emotional depth, we hope audiences look forward to this new version.” Gain and Jo Kwon’s voices distinct yet complementary are expected to evoke a warm, nostalgic atmosphere, making the duet particularly fitting for the winter season.
