The front row audience at Rainbow's concert probably never expected this level of 'fan service'.
According to Koreaboo, a clip has been circulating online, showing Hyunyoung spitting water all over their fans at a concert.
In the video clip Hyunyoung walks up to her fellow moment, pointing to her inflated cheeks.
Nobody really realises what she is about to do, and without warning, she sprays water all over them.
Her members burst out with laughter at her silly prank.
Responding to the video, some fans have written creep-level adoration comments like: "If only she spit into my mouth, then we would have indirectly kissed."
Seems like the fans loved it.
