Oh yeah. Busan (Pusan) turned in JYJTown as thousands and thousands of fans converged on the city for the JYJ concert held June 11 2011.

The fans obviously had a great time, but he guys also seemed to have had a great time too.  Check out a clip of Yoochun's great time:

Tee hee! Now, now, don't get jealous.  These are gorgeous young men. Let them have fun too!

Sajik Indoors Gymnasium made a daebak (T/N: a Korean word for great success) with the JYJ Concert.

On the 10th, the City of Pusan’s Gymnasium Facilities Management Industry Office revealed that when combining the 10% of entrance fees which it receives as the rental fee and also the exclusive usage fee, the total profits are over 200,000,000 KRW (approximately 200,000 USD). For the 2-day concert, about 20,000 tickets that average 100,000 KRW (approximately 100 USD) each have become completely sold out. Such profits are about 6 times of Seo Taeji’s Pusan concert that was held in June of 2009 (audience if 5000, rental fee 33,000,000 KRW i.e., approximately 33,000 USD). Sajik has raised its largest profits in ten years for a single event.
