KT said on June 19 it will offer customers who have used its combined mobile, internet and TV services for at least 5 years a chance to attend the musical "That Day" on July 25 at D-Cube Link Art Center in Seoul.

"That Day" is an original musical based on the songs of the late Kim Kwang-seok, set against the backdrop of the presidential security service at the Blue House. Actors Um Ki-joon and Yoon Si-yoon will appear in the performance.

KT will run a four-cut sticker photo event using the production concept on the day of the show, along with a social media event. It will also provide invited customers with special photo cards and a program book.

During the professional baseball season, it will run a "Camping Zone Invitation Dream" benefit at Suwon KT Wiz Park. The program lets people camp and watch a game in a dedicated tent inside the ballpark. Up to 4 people can use it per team. Invited customers will be provided with a four-person tent, camping equipment and a barbecue meal.

Applications for the July Invitation Dream can be made through the long-term customer benefits page on KT.com until July 8. Winners will be notified individually on July 13.

KT also operates "Coupon Dream", which offers discounts, along with Invitation Dream, an experiential program. Coupon Dream includes a 3,000 won discount for Millie's Library, 2 GB of data, and a one-month V Coloring pass.

Kim Young-gul (김영걸), head of KT's Customer Business Division, said, "We prepared the event to express our gratitude to customers who have used KT for a long time." He added, "We will continue to listen to customers' voices and raise service satisfaction."
