First of all, I'm glad you enjoyed the performance.

Thank you for your valuable feedback.

We have improved the system so that you can log in from within Korea until the day of the performance.

We apologize for any inconvenience this may have caused.

We have confirmed that a copy of your ID will not be required at the counter, so we are only sending reservation confirmations and personal information to customers who have made reservations for the third round and later.

Presumably, the person you saw presenting a copy of their ID probably didn't understand Korean and simply presented what they were told to present in advance.

We would be grateful if you would use our services again if you have the opportunity.

Thank you for this time.
