Okay so, as some of you might or might not know, I'm half Dutch and half Colombian, and as latina, I have my musical tastes. So I was listening to one of these music groups, and I think this song is literally Eren and Mikasa after Eren tells her he hates her, but we obviously know it wasn't true. So my headcanon is basically Eren dedicating this to Mikasa.
(Obviously translated to English)
The song is called Yo no merezco volver by Morat (or well, I don't deserve to come back.)
Erase my name from every phrase you say
Stay silent if you're going to call me again
Don't speak of me in vain if your heart is still half broken
Because I don’t deserve to come back
Burn my photos, it’s not fair that I still remain in your life
Lose my shadow if it comes back to follow you again
Close all the doors that were left open when I left
Because I don’t deserve to come back
Because I haven’t forgiven myself
Give my poor conscience a break
Because I don’t deserve to come back
You’ve earned the right to hate me
And making it easier for you will be my duty
No one has ever invented a god that can redeem all my sins
And I don’t deserve to come back
Because I haven’t forgiven myself
Give my poor conscience a break
Because I don’t deserve to come back
Give my poor conscience a break
Because I don’t deserve to come back
