BTOB's Seo Eunkwang has released a motion spoiler video ahead of his solo comeback single 'OUR YOUTH (Our Youth)'. BTOB Company unveiled the analog-sensibility-filled spoiler video through SNS channels on the 4th, featuring a transition to a classic film frame accompanied by camera shutter sounds, visually conveying the emotions of youth and cherished memories. The handwritten text in the video poetically describes summer scenes outside a window, children playing in an elementary school playground, and laughter of students in uniforms—evoking viewers' own school day memories in an essay-like manner. 'OUR YOUTH' is a new album that archives one page of pure and passionate youth that everyone holds dear, sung in Seo Eunkwang's clear and refreshing voice, with tracks filled with the temperature and seasonal feeling of youth. On July 26th, Seo Eunkwang held a solo outdoor busking concert '2026 SEO EUNKWANG 〈REC : Feel Alive〉' at the Forest Stage in Seoul Children's Grand Park, where he surprise-premiered the new song and conducted a meaningful sharing project by donating part of the ticket sales priced at an affordable 10,000 won. The single album 'OUR YOUTH' will be released on all major online music sites at 6 PM on the 6th.
