BUSAN, Sept 17 — Busan is set to host a major event in October: a BTS concert. This performance, highly anticipated by fans of the K-pop band, is posing challenges for the largest city on the South Korean coast, both in terms of accommodation and transportation.

Busan expects fans of BTS, commonly known as ARMY, to flock to see their idols. Especially since the group announced in June that it would be taking a break so that each of its seven young members can focus on their solo careers.
