With regard to CC x Lelouch (or CluClu), you'd never realize that they were only conspirators by either R2 or the artwork.
I'm still trying to figure out how the heck Lelouch is supposed to fulfill CC's dream of being truly loved by someone (romantically) and yet not be in love with her...???
That's like saying you are going to give someone a ride in your car but refuse to let them in it.
Oh, and Lelouch x Harem forevah!!!
