Kim Go-eun answered, "I've been listening to this song called 'Butterfly' by BTS. I heard it by chance and it was just so good."
When Jung Hae In heard Kim Go-eun say 'Butterfly', he went "Oh!" and nodded as if he knows the song and also finds the song great.

After making this remark though, Jung Hae In suddenly blushed and laughed shyly.
