It's time for MAGIX to take the lead - on and off the stage. The new 'it' K-pop girl group receives news that could change them forever. What will they do to make sure that they remain the quintessential quintet girl group within their agency? Hasoo Kim, the power hungry CEO of The Rising Moon, finally tracks down the person responsible for stealing away his prized staff, only to find that it is the one who first broke his heart many years ago. STARZ, the chart topping K-pop boy group, set their sights on their comeback tour in Korea, before their leader enlists in the military and one member in particular is hoping that MAGIX comes along for the ride. Can the former 'gimmick' girl group make sweet music once more? Or will their chances of going further end on a sour note?
