Destined to die, yep. Admit it, romance has no chance in hell of surviving in Code Geass, because the creators love killing characters. Neither Suzaku or Lelouch will survive Code Geass. Neither will Li Xingke, Cornelia, Orange, the Knights (including Gino), Rolo, Kallen, or the Emperor. The only character I think will survive is Nunnally, and I'm not even 100% about that.
