Young K of DAY6, who is known for his big appetite, has been chosen as the new ambassador for Subway.

On April 22, Subway unveiled a teaser video featuring Young K on their official Instagram and other platforms. The clip shows Young K in a green cardigan—the brand's distinctive color—wearing wired earphones. In a surprising moment, the word "턱!" (a Korean term for a sudden drop or thud) descends in bright yellow letters, catching Young K off guard.

The video concludes with Subway’s recognizable sound, similar to the one Young K had previously shared in a video titled "KickFlip JYP Debut Masterclass I EP.1 Young K" released on January 27 via the KickFlip official channel.

The online community reacted positively to the ad, praising Subway's choice with comments like “Subway has excellent taste,” “The best model,” and “Young K and Subway are a perfect match.” DAY6's latest success with "You Were Beautiful" has helped them secure various advertising partnerships. In an interview, the band expressed gratitude towards their loyal fans.

Sungjin, the group's leader, shared a thoughtful message: “I believe that every success comes after facing challenges. Despite the timing being different for everyone, retaining hope can lead to achieving one's dreams. This has been true for us as well.”

Young K added, “The core of DAY6's music revolves around time. Instead of rushing towards a fixed destination, we have flowed with time, culminating in our creations thanks to the collective effort of each member, our supporters, and every My Day (our fans).”

Currently on their 'FOREVER YOUNG' global tour, DAY6 is scheduled to perform 45 shows across 23 cities worldwide. They are set to perform in Yokohama on April 26–27, followed by Jakarta on May 3, with their tour conclusion at the KSPO DOME in Olympic Park, Seoul, on May 9–11 and 16–18.
