Faqs

What is included in the “Chocolate Distribution” event after the concert?

Since the Yokohama performance falls on March 14th (White Day), Kim Sejeong will personally hand out chocolate gifts to fans during a send-off session after the show concludes. This benefit is included for all valid ticket holders attending the performance.

Are there any age restrictions for children attending the Yokohama fan concert?

Preschool children are not permitted to enter the venue under any circumstances. Children aged 3 and older require their own ticket for entry, and all minors must be accompanied by a guardian to ensure a safe environment.

How does the separate drink fee at KT Zepp Yokohama work?

In accordance with Japanese “Live House” venue policies, all guests must pay a mandatory drink fee upon entry. This is paid in cash at the door, and in exchange, you will receive a drink token for a beverage inside.

Can I choose my specific seat number when applying through the concierge?

For this performance, all seats are assigned via a lottery or reservation system rather than manual selection. Your seat number will be finalized and issued through the official ticketing platform approximately one week before the show date.

What happens if the artist cancels or the performance schedule changes?

If there is an official cancellation or a significant change to the event schedule, we will coordinate with the organizer on your behalf regarding the refund policy. Please be aware that personal cancellations by the ticket holder are typically not eligible for refunds.
