This poem talks about a situation when you think you've found the right person for you, but then later realize that it was just a made up illusion created upon you by him.
I never imagined to love an unexpected man in an unexpected place. You gave me light, you opened my mind and break through my walls... You had shown me the way to love and yet I haven't spoken of my heart... I never imagined to lose you in a way I had let you down.
