Because it was the favourite song of her crush from middle school.

On July 7th, Kim Chang Wan, IU and Akdong Musician made their appearance on 'Healing Camp'. The MC asked IU why she chose to remake Kim Chang Wan's "Meaning of You" in which she made a surprise confession be saying that she used to like a man when she was in middle school and it was his favourite song.

Kim Chang Wan thought she made a mistake and corrected her by saying it should be a boy not a man, to this IU said once again that he was an adult man.
