50 free Loona trivia questions with answers — music quiz, new questions added Oct 2026.
Loona did not arrive the way most K-pop groups do. Over a year and a half, the members were introduced one at a time, each with a solo single of her own, then gathered into sub-units before the full line-up finally shared a stage in 2018. The slow reveal built a devoted international following and a web of storylines that listeners still pick apart. This quiz covers the whole story: who each member is and which release introduced her, the sub-units and their records, the group's best-known singles and chart milestones, its turns on television, and the contract dispute with its label that led the members to regroup under new names. It is written for longtime followers who know every member's story, and for newer listeners who found the group through its spin-offs and want to see where it all began. Every answer comes with a short explanation, so you finish knowing a little more than when you started.
