FIESTAR say 'I Don't Know' with the release of their comeback MV + single album

Singing, "I Don't Know", their title track by their new CEO Shinsadong Tiger, the girls intrigue with the incorporation of the familiar melody heard in children's songs.

Their agency Collabodadi previously remarked regarding the girls' concept, "Rather than an overtly revealing concept, the title track, 'I Don't Know', gives off a sexy appeal through its metaphorical expressions... It's a sexy concept hidden within their cute charms," so see if you agree as you take a look at their MV above!
