Felix and Hyunjin

There was always talk that people had guardian angels, which seemed completely ridiculous to you, until something would completely change that opinion. As you always find yourself in your room, until you heard noises in the living room of your house, it was strange since you lived alone and had no pets. With fear you left the room opening the door a little, seeing how there were two boys standing there, both with wings; one with white wings and another with dark wings, what were those strange kids doing there?
