I saw this comment some time ago and it said "Honestly, I cannot imagine Jumin or Jaehee without the other. If you find Jumin, you find Jaehee and if you find Jaehee, you find Jumin. Which is why I was really conflicted during her route. I felt like I split up something really important. I can't imagine one without the other, I really can't!" I don't know where I saw this and why I ever remember that much of the comment. All I know is that this comment I found was in my earlier days of Mystic Messenger and this song came into my mind and I thought "HOLY SHIT THIS SONG FITS THEM!!!" So here you go.
