DK and Seungkwan, the main vocalists of the group SEVENTEEN, have brought warm comfort and laughter to fans through a special "Bonus Book."

In the "Ordinary Notes #Bonus Book" video recently released on SEVENTEEN’s official YouTube channel, DK and Seungkwan shared records of their daily lives and engaged in a sincere conversation about music and life.

By opening up about their small thoughts, they shared the inner selves of "Youth Dokyeom" and "Youth Seungkwan," which differ from their glamorous personas on stage. Moments where they expressed their concerns as vocalists and mutual respect for each other's voices offered a glimpse into the root of SEVENTEEN's solid talent. Their conversation in a cozy space provided viewers with a sense of comfort, as if listening to the stories of close friends.

Fans who watched the video reacted with comments like, "Just hearing their voices is healing," "I love SEVENTEEN's unique sensibility that makes ordinary life special," and "I hope DK and Seungkwan's friendship lasts forever."

In particular, the "real brothers" chemistry—where they playfully bicker while praising each other’s strengths—is highlighted as the key "killing point" of the video.
