You have just debuted in a girl group A.R.M.Y as a rapper  and a leader under the same company as BTS. Turns out, that both you and Rapmonster (your ultimate crush and the reason you joined BigHit) like to use the recording room when your schedule is empty and create music. Little do you know, music is the last thing you will create in that room. Rapmonster knows that the company is up to something shady and illegal. Will you help him knowing that your entire career is at stake or will you just mind your own business and let Rapmonster deal with his own issues?
