EXO's leader Suho's ring-tone service for the forthcoming Daegu International Musical Festival (DIMF) rapidly sold out, according to Daegu News.

"We didn't expect (the sound service) will be sold out so fast because it's distributed by first come first served basis. Suho's popularity has been greatly felt as many people gathered, and the server is temporarily down," states a DIMF official.

Suho also appeared in a promotional video prior to this for prospective attendees to take part in the biggest musical festival in South Korea. Because of this, the number of followers of every DIMF social media accounts significantly increased.

Almost a month ago, Suho was declared as the honorary PR ambassador for the upcoming prestigious festival. DIMF Chairman Lee Jang-woo shared in an interview that Suho's contributions to the musical theatre industry and his immense popularity will bolster the affair.

"EXO's Suho, who is loved all over the world, is expected to maximize its synergy by participating as DIMF's goodwill ambassador and as a musical actor," he said. "We want to make DIMF a cultural industry brand representing South Korea. We want the festival to have even more interest and participation with the help of Suho."

The 13th DIMF is slated to kick-start from June 21 to July 8, 2019. There is also a high possibility for Suho to visit the event. Not just by Korea but performances from other countries are expected to partake in the event. The affair also hopes to open tickets for music enthusiasts around the globe, such as the ones from France, Britain, China, and Spain.

Apart from being the leader of the K-Pop supergroup EXO, Suho has also been active as a musical theatre actor, having headlined large-scale musical shows such as "The Last Kiss" as Rudolf in 2017 and "The One Who Laughs" as Gwynplaine in 2018, which bagged him three awards.

In an interview, Suho revealed why he chose the latter as his second musical involvement. He shared, "Not a year has passed since my debut as a musical actor. I was interested in 'The Man Who Laughs' even before I started to practice for 'The Last Kiss.' I wanted to see the script so badly."

The idol-musical actor added, "I like the Joker character very much, and the Joker is a character derived from 'The Man Who Laughs.' I wanted an opportunity to audition for that character, and I was lucky enough to be cast for the role."
