After dj E.den hosted arirang radio for a week due to Dj Sam's short departure, two teenage girls came up with a plan they call: 'mission impossible'. They themselves were going to visit Seoul, Korea in order to meet and Keep their kpop idols. They have so many biases from different groups; LC9, Lunafly, Exo and infinite. They each steal one member from each group. They do the unthinkable to achieve this goal. It's fair to say both Crystal and Mary are the two obsessed kpop girls who literally turn from good to bad. What lengths will they go to, to achieve their goal? Will they do it or will they just epicly fail? (Inspired by Dj. E.den's hosting)
