As Our Worlds Collide (Shownu/I.M)

Lim Changkyun or better known as radio announcer, I.M. always finds himself hiding behind the microphone in a radio booth. He's very shy, timid and most of the time, afraid of people judging him just by seeing him in person. That's why his identity is hidden. During one of his broadcast, he receives a call from a man, asking for an advice about an ex-girlfriend who cheated on him while he was serving in the army. Changkyun felt bad for the man and he gave him an advice that he believes should be taken to heart.
