Fans are demonstrating that when it comes to their idols, they no longer want to give stuffed animals or small items -- they're concerned for their idols' health, and seek to give them strength through good deeds, health supplements, and lunch trucks. f(x)'s Krystal was the latest celebrity to receive such a thoughtful gift, as fans visited her on the set of her sitcom, 'High Kick 3', with an elaborate lunch truck for her fellow cast and crew. On October 16th, Krystal updated her Me2day with two photos and thanked her fans for the support. She wrote, "I ate the food deliciously~~ Thank you so much ? Our fans are the best!!:)" The banner over the truck says, "Whether you have long legs or short legs, come on over! Maknae Soojung is treating you to lunch!!!!!!!" Fans spammed the comments section with the sitcom's popular aegyo catch phrase, "Bboo-ing, bboo-ing!" Source + Photos: Krystal's Official Me2day
