News1 reported on April 13 that the two idols will be releasing a song together. The news outlet shared they recently finalized the discussion for the duet song and started to prepare for recording.
Jun Hyosung’s agency confirmed the report on the same day, saying, “Jun Hyosung will form a project group with Yubin. Since it is still in its early stages, no details have been set, including when the new song will be released.”
Yubin is a former member of Wonder Girls, and she established her own agency in February. Jun Hyosung is a former member of Secret, and she is currently acting in the drama “Memorist.” The two were part of a girl group called Five Girls that included former After School member Uee, former SPICA member Yang Jiwon, and solo singer G.NA, but the group disbanded before their scheduled debut in 2007.
