Singer IU and her agency, LOEN Entertainment, have once again amused fans as they were seen having a "verbal battle" on Twitter.

To celebrate Sunny Hill's comeback with their title song "Is the White Horse Coming", LOEN Entertainment wrote on their official Twitter, "Receive an Asea Prinsoo t-shirt just by requesting Sunny Hill's 'Is the White Horse Coming' on the radio! 10 winners will be selected and will receive a signed Asea Prinsoo t-shirt."

Upon seeing the mini radio event, IU showed a lukewarm reaction by replying, "Who would request the song just to receive that t-shirt!!" Her agency immediately tweeted back with, "Singer Ms. IU, you're making things difficult if you behave like this," and attached a photo of IU poking her head out the window of a car while wearing the t-shirt as if she was bragging.

IU later changed her tone and showed her support for the event by tweeting, "Everyone, please send in lots of requests^^."

Fans who came across their conversation commented, "They both are hilarious," "I'll be requesting," and "Then why are you wearing it IU? Keke."
