On April 25th, Loen Entertainment said through their official Twitter, "Listen to Sunny Hill's 'Is the White Horse Coming' on radio and receive an Asia Prince [songwriter] tee-shirt! We'll pick ten people from the listeners and give away tee-shirts autographed by Sunny Hill."
IU replied to this with an unenthusiastic tweet, saying, "Who will tune in just to receive that!"
Loen Entertainment then followed up with another tweet, saying, "Dear artist, saying that puts us in a bad spot." They also accompanied their tweet with a photo of IU proudly showing off an Asia Prince tee-shirt.
With that, IU ended the short episode with a tweet, "Everyone, please tune in", causing much amusement to her fans.
