The beauty of TKEM is that they actually introduced multiple universes for one to play with. While they're not actually the gang, but doppelgängers of a different universe than presented in the drama.

When I first saw the still of Lee Min-ho and Jung Eun-chae, I also saw instant chemistry. No lies. I'm intrigued by the potential of the crackship pairing. And since both Lee Gon's and PM Koo's doppelgängers were criminally underused, I decided to give them a chance . . . albeit, in another different universe, as different characters. I tried. Enjoy.
