Doyoung and Seungkwan of the group Seventeen are gaining attention with their karaoke content. Since releasing their first mini-album "Soya-gok" on January 12, the two members have presented numerous audience-participation content. They sparked explosive reactions on social media through the "Blue" duet challenge, which allows participants to harmonize. The recently released karaoke content features a video recreated with a "B-grade sensibility," where the honestly recorded backing track and the natural scenery serve as points of interest.

Riding the popularity of this unique content, the "Blue" challenge is becoming active again. Since the song requires a high vocal range, long breath control, and delicate emotional expression, it has stimulated the desire to take on the challenge. Along with the revival of the challenge, the song itself is gaining word-of-mouth popularity. In fact, "Blue" ranked number one on Instagram's "Rising Popular Audio" and topped YouTube's "Trending Music" as the duet challenge spread.

Attention is focused on the possibility of "Blue" joining the ranks of "karaoke favorites," a representative indicator of a ballad's success. Content applying "Blue" to everyday moments is also receiving positive responses. The YouTube channel "Nerdult" produced a comedic short movie comparing the regrets felt right after a breakup to the lyrics of this song, drawing empathy from many. This is a notable example of synergy between music themed on "ordinary love" and reality-based content. Doyoung and Seungkwan appeared in this video themselves, adding to the fun.

On social media, short-form videos featuring personal love stories such as "breakup tales" and "ex-boyfriend stories" paired with "Blue" are spreading. Doyoung and Seungkwan plan to continue the success of "Blue" with various content. On the 22nd, Doyoung will appear as a guest on the web variety show "Buseungkwan's Bibidibabidu," hosted by Seungkwan, showcasing their unique "tikitaka" chemistry. On the 23rd, "Hyel's Club," featuring Doyoung, is scheduled to air.

In this way, Doyoung and Seungkwan are continuously expanding the popularity of "Blue" by communicating with the public through various methods. Their activities strengthen their connection with fans not only through music but also through diverse content.
