At least that's what the panelists on a recent episode of 'I Heard a Rumor Show' theorized. Lee Sang Min began, "Many stars have had close encounters with supernatural forces. There are even myths that artists who witness ghosts in the studio will produce hits."
Stephanie chimed in, "There is a rumor that IU earned the 'Nation's Little Sister' title after meeting a ghost in the studio. During the time she was recording for 'You and I,' she saw her manager go into the studio so she followed suit but there was no one there."
Choi Yeo Jin asked, "Then who was it that [IU] saw go into the studio?" Stephanie answered, "IU thinks that she saw a ghost, and she revealed later that her manager was elsewhere. But after she saw the specter, 'You and I' became a huge hit, and IU made her place in the entertainment world as 'Nation's Little Sister.'"
Hong Suk Chun jokingly added, "So 'You and I' became 'Ghost and IU,' huh?"
