[talk] MJ, you're challenging yourself to rap on 'The Mission: K'! I have to go see it!

Our Astro's MJ will be appearing in the musical concert 'The Mission: K'.
He is the main vocalist of the team, but he says this is his first time trying rap.
I'm already excited and looking forward to how cool it will be.
It's being held at Sejong Center for the Performing Arts from January 30th to February 1st.
Let's all go see it together and support MJ's new challenge!
