During the tvN Chuseok special 'Eight Provinces Wandering Band', Juniel sang her heart out to her own song written after experiencing her first breakup titled, "Everlasting Sunset". She introduced the song saying, "The song that I will play now is a song I wrote after experiencing my first breakup in my 3rd year of middle school."

The song touched the hearts of the cast with its lyrics about the beauty of love, the pain of farewells, and the longing for the past love. So naturally, the cast got curious about her experience and tried to dig more into what kind of significance this mystery guy holds in her heart.

Juniel blushed as she revealed, "He's an oppa I knew and dated for a bit." When asked, "Do you ever get curious about him?", she shared with a chuckle, "No. I purposely don't try to find out about him."
