Lelouch had killed Euphy. Lelouch had killed so many innocents. His best friend had turned into a sworn enemy. So, of course, he silently clenched his fists at the sight of him smiling. Did he even deserve to smile? After all the grief he'd brought upon?
It was only typical the happiness on his face made Suzaku evidently frown.
But why was it that the frown grew deeper when someone else made that very same happiness possible?
Well, this was inspired by that scene where Suzaku seemed to be jealous when he saw Lelouch and Rolo interacting. My poor boy :(
