Link to original Marian & Mariel cover:
I had already decided to use a female cover of this song for a video celebrating Yi Seo's "birthday", but the versions I had been looking weren't what I wanted (though it's quite difficult to replicate Luis Miguel's powerful vocals); but luckily, this cover just happened!
Somehow I remembered this song and thought it'd be good for encapsulating Yi Seo's feelings at the end of episode 11. Later on, I had this idea of adding a hypothetical rant to her shrink. Hope you like it!
