On the radio interview, Woohyun told the listeners that L and Sunggyu argued about the concert location. L suggested Sunggyu to hold the concert at KSPO dome, while Sunggyu were afraid that the dome would be too big. Sunggyu said it would be better to take a middle capacity but full seated than in big hall but would be empty seats. But L was persistent with his opinion. Even the group was divided into two, L's team and Sunggyu's team. After a long discussion, at the end L's idea was approved by all of the members. And voila now we know that all of the tickets in KSPO dome have been sold out!
