DAY6's Dowoon appeared on Elle Korea's YouTube channel 'Chem Workshop' on the 27th to share behind-the-scenes stories from Netflix series 'Why We're Going on a Mountain Hike.' Dowoon appeared alongside Cardi Garden, Lee Chae-min, and Tarzaan from All Day Project, revealing he felt 'confused' when first learning about the mountain hiking appearance. The four members rated their chemistry at 100 points and explained their individual roles: Tarzaan found restaurants while Dowoon handled driving duties. Cardi Garden served as the mood maker, turning complaints into comedy, while Lee Chae-min maintained a peaceful atmosphere that earned the production staff's favor. Dowoon expressed willingness to appear in season two, but Cardi Garden initially refused, saying 'if it involves hiking, I can't,' before laughing while suggesting it would be possible with the same members.
