During the episode, Kim Bum Soo almost got eliminated at the first round. The first mission song was “A Day” and Kim Bum Soo received the second most votes to be eliminated, despite singing his own song.
After he revealed himself, he sang “Last Love” for the final round. During this time, he shared that the song was actually taken from his own experience.

Then the MC Jeon Hyun Moo exclaimed, “I just got goosebumps. Were the tears real then?” Then Kim Bum Soo answered, “My love history is simple. My first love was my last love.”
Kim Bum Soo also revealed that he broke up with his girlfriend to become emotional for his song, “I Miss You.” That girlfriend was the same person behind “Last Love” as well. Kim Bum Soo added, “I should say this carefully, but that girlfriend was my muse for my music.”
