On June 26, IU’s label EDAM Entertainment posted a video of IU having a “mishmash” session on its official YouTube channel.
“I received requests from fans in advance,” IU said. “I thought they would still request my songs, but there were a lot of songs that I didn’t expect.” IU introduced her first song, saying, “First of all, I will sing OH MY GIRL‘s ‘Dolphin.’ I really like this song.”
After singing the highlight of the song, she said, “I wonder if OH MY GIRL saw this. I feel relieved that I made no mistakes.”
She then covered snippets of DAY6’s “Zombie,” Jukjae’s “Letter” and “Lullaby,” BTS’s “Spring Day,” Baekhyun’s “UN Village,” and JeA’s “Greedyy” (for which she wrote the lyrics).
Later the day, OH MY GIRL’s Hyojung posted a screen capture of IU singing their song and wrote, “What’s going on? I feel like I have the whole world. You’re the best.” To the part where IU mentioned the group, she wrote, “We’re not just listening to it, but crying. Thank you so so much.”
