one is Felix's Deep End, and the other is Jo Yuri cover of Sunwoojunga's Run Away
Deep End is about the pain of losing someone who have been the integral parts of your life, someone that fill the void in your heart
While Run Away is about taking someone away from their misery so that they can have a moment of respite, and then facing it again with a better condition.
One is telling a lost, one is telling someone who comes for you.
if you listen to Deep End first, and then Run Away...
Then it kinda becomes some sweet story, where someone tries to help the other one in agony. A healing.
and if you listen to Run Away first and Deep End next,
Then it kinda becomes a tale of tragedy where this person who have became the light of another life, left. Leaving a deep scar.
it's beautiful.
