Fics like Rise of the Unholy Trinity

The Zero Requiem was successful, but to some, the price was too high. C.C. does not care about world peace, not when she has lost the last person who gave her existence meaning. Suzaku Kururugi takes refuge in the last orders from his emperor, but he aches for what could have been. They hate each other, but in a world that so eagerly accepts Lelouch's sacrifice without thanking him for it, they cannot help but take refuge in one another. And when C.C. hatches a plan to turn back time and bring Lelouch back, Suzaku eagerly welcomes it. She will be his shield and he will be his sword, and this time, they will get it right.
