According to allkpop, the mystery photobomber turned out to be labelmate NU'EST's Ren who looked like a girl group member in his makeup, wig, and dress for Boy's Day's cover of Girl's Day's "Something".
UEE, who couldn't join her members on stage due to filming for 'Golden Rainbow', made sure not to miss out on the family reunion backstage.
