On March 25 (KST), EXID shared a short clip of Hyerin inside the recording booth, singing her ad-lib to their upcoming title track 'Do It Tomorrow'.

But, instead of doing an ordinary, vocalized high-note as an ad-lib, Hyerin sung two high notes, letting out what sounds more like cute squeals than an ad-lib. 

After asking the producer if she had done it right, she shrieked again, but for real this time.

Hyerin's short but cute video left viewers comment, "She's so adorable?" "Reasons why i love Hyerin...she could make me smile so hard in 14 seconds" "what is this?????"

Are you excited for EXID's comeback?
