Key elements included: 1) Choosing a red background to symbolize love and passion for the storyline. 2) Placing a cracked mirror in front of the actor to represent his distorted past and broken life. 3) Editing an image of a happy couple and placing it in the cracked mirror, faded to represent a memory from the actor's past. 4) Including details like a shadow and title to convey that this was a promotion for a club song called "On & On".
