The fan group is then given updates from the food truck vendor on how things are going.
"We were told that Hyun Bin personally visited the food truck to get his food and drinks. He spent some time reading our banners and watching the video edit playing on the truck and then said his thanks," the spokesperson said.
Some artists choose to thank fans by posing with the trucks but in this case, actor Hyun Bin is not on social media aside from his agency's Instagram.
Getting your favourite idol higher in the charts slot wallet
If there's one way to say thanks to your idol, it's by getting them higher in the charts. This is done by promoting the artist's music on social media, requesting radio plays and buying the music, sometimes on multiple platforms.
Other groups host competitions where fans can win items if they purchase music in support of their idol. Some even raise money so that fans who can't afford to buy the music themselves, have the funds to do so.
USA Ahgases, a group dedicated to the band GOT7, is currently finding ways to support members of the group who are currently working on solo projects.
"We are trying to find ways to make them go higher," an admin of the group said. "We have some items like making keychains, lanyards etc, things that Ahgases could use every day".
