SEE ALSO: IU to become the first Korean solo artist to hold a show at the Philippine Arena in June

On the June 3 edition of 'Sketchbook', DEAN shamelessly talked about his love towards IU. At MC Yoo Hee Yeol's question on the K-Pop artist he most wants to collaborate with, DEAN answered immediately, as if he was just waiting for that question, "IU." DEAN went on to explain his loyalty for IU with a weird analogy, saying, "When an elephant performs tricks with its trunk, people enjoy it, correct? But that wasn't the elephant's design," drawing a tinkling of confused laughter from the audience with his odd comparison of IU to an elephant.

DEAN added, "I even have a song written for IU," and sent a personal message to her. He said, "I can't show you on TV, so please contact me." 

Perhaps we should be looking forward to a DEAN x IU collab some time soon?
