BTOB's Yook Sung-jae revealed the second main poster for his 2026 solo fan meeting "5 to 7 Five to Seven" through his official social media on November 10. In the poster, Yook appears as a busy office worker in a suit with an employee ID around his neck and a stack of documents in his arms, alongside the line, "Only one goal: leaving on time. I will clock out right on schedule!" While the first poster depicted the rush of a morning before work in bed, this one focuses on running toward an on-time departure. The fan meeting will be held at 7 p.m. on December 11 and 6 p.m. on December 12 at Ewha Womans University's Main Auditorium in Seodaemun-gu, Seoul. Yook will present various segments and stages revealed to fans for the first time, and after the show he will hold a "hi-bye" event to greet every audience member up close. Last year, Yook played a dual role in the SBS drama "The Haunted Palace," winning the Excellence Award at the 2025 SBS Drama Awards, and he was named the most anticipated actor at the 2026 Korea First Brand Awards. In the new SBS Wednesday-Thursday drama "Nine to Six," premiering on November 25, he plays Han Sun-woo, an intern on the legal team of an automobile company. He also continues his activities with BTOB and released the new song "Us Again" this year to mark the group's 14th debut anniversary.
