Lee Hyori's fans are begging the pop diva to add an additional showing of her concert due to the recent sell out. Hyori's upcoming concert will be her first solo concert since her debut 10 years ago. And since this is her first concert ever, she wants everything to be perfect and deliver an exceptional performance. Being that it will be a 2.5 - 3 hour solo concert, her management company feels that an additional concert may be too exhausting for the pop diva. However, they stated that Hyori will give it serious thought before making her final decision. source: allkpop
