On the May 18 broadcast of MBC's 'Picnic Live', IU described a memorable encounter she had with her dear fans.
She shared how she enjoyed interacting with fans, as well as how she pondered about bringing her fans satisfaction.
The singer then recalled a rather emotional incident, "I got emotional when fans sang 'Heart' during my concert. 'Heart' is one of the songs that emerges when I think about pure and righteous thoughts. Maybe that's why it gets me every time fans serenade it."
