BTS’s Jin has unveiled his latest project — the Challenge Book, a 32-page collectible packed with activities, missions, and memories from his iconic #RUNSEOKJIN_EP.TOUR. This creative release blends humor, nostalgia, and fan participation, turning the connection between artist and audience into a hands-on, emotional experience designed exclusively for ARMY

Jin has once again proven why he’s one of the most beloved and inventive members of BTS. His new Challenge Book, announced by BigHit Music, offers fans a completely new way to experience his solo journey — not just as spectators, but as participants. Inspired by his sold-out #RUNSEOKJIN_EP.TOUR, the book invites fans to relive the most joyful moments of his performances through mini-games, missions, and creative challenges that reflect Jin’s signature mix of wit and warmth.

According to BigHit, the Challenge Book is more than just collectible merchandise — it’s an interactive keepsake designed to spark laughter, connection, and creativity among fans worldwide. Inside, readers will find ten themed “missions,” including RUN ARMY, a race to arrive on time for the concert; SING ARMY, a playful karaoke roulette; and ANSWER ARMY, a memory quiz celebrating the funniest and most emotional moments from Jin’s solo shows.

The book also comes with a colorful photobook, crayon set, stickers, mission roulette, and exclusive photocards, making it one of the most detailed and engaging BTS collectibles ever released.

Pre-orders for Jin’s Challenge Book open on January 9, 2026 (KST), with the global release scheduled for January 26, 2026. Fans can purchase it through the official BigHit Music store and select retail partners, though expectations are that stocks will sell out within hours.

The concept perfectly embodies Jin’s artistic identity — humorous, heartfelt, and always deeply personal. Known for his playful charm and genuine love for fans, Jin has continuously found ways to blur the line between idol and friend. The Challenge Book extends this relationship into a tangible experience: ARMY can revisit the excitement of the tour, test their knowledge, and share their results online, turning the entire fandom into a creative, collaborative game.

As one fan commented on Weverse, “Only Jin could turn a concert into an adventure and a book into a memory you can play.”

This project also highlights Jin’s growing creative freedom as a solo artist. After years of global success with BTS, he’s exploring new forms of storytelling that go beyond music. The Challenge Book isn’t about performance or promotion — it’s about building emotional connection. It celebrates Jin’s humor and compassion while reminding fans why his presence in the BTS universe is truly one of a kind.

The Challenge Book’s design — featuring pastel tones, doodles, and handwritten notes — mirrors Jin’s warm personality and his love of detail. Each page feels intimate, like a letter from him to ARMY. Whether it’s a drawing prompt, a reflection space, or a hidden trivia challenge, the experience radiates the comfort and laughter he’s known for bringing to every interaction.

For ARMY, this isn’t just another collectible — it’s a bridge to the joy of #RUNSEOKJIN_EP.TOUR, an event that fans still recall as one of the most heartfelt solo projects in BTS history. It’s an emotional scrapbook that lets them keep the tour alive, page by page.

BigHit Music praised Jin’s creative involvement, noting that he personally contributed ideas to every section of the Challenge Book. “He wanted something that fans could actually use, not just display,” said a company representative. “It reflects who Jin is — imaginative, funny, and deeply connected to ARMY.”

The release underscores a broader trend in K-pop: artists creating interactive, story-driven experiences that deepen their bond with fans. But Jin’s version stands apart — playful yet sincere, immersive yet comforting. His Challenge Book doesn’t just celebrate fandom; it redefines it.

Social media platforms have already exploded with excitement. The hashtags #JinChallengeBook, #RunSeokJin, and #JinForARMY trended globally within hours of the announcement, with fans praising the idea as “the most Jin thing ever.” Many shared nostalgic photos and memes from past concerts, turning the pre-order period into a collective celebration.

Through this project, Jin reminds fans of his unique philosophy: creativity isn’t about scale — it’s about sincerity. Whether through music, laughter, or a simple book of challenges, he continues to inspire millions to connect, express themselves, and smile.

As the Challenge Book prepares for release, one thing is clear: Jin doesn’t just create content — he creates community. And in the world of K-pop, that’s what makes him truly irreplaceable.
