TWICE are quickly climbing up the hill to success with no hint of slowing down anytime soon!

Their MV for debut track "Like OOH-AHH" has now hit its 5 million views mark on YouTube within six days, which is an incredibly impressive feat for a rookie group. It probably helped at first that everyone was curious about JYPE's new girl group, but only their hard work accounts for their continued success days after the fact.
