Why do I get the feeling that Rai is some sort of Mary-Sue Character?

I remembered seeing this a long time ago on Youtube. It's from the Nunnally love ending, where Rai becomes Nunnally's boyfriend, to an extent. Lelouch is being the over-protective big brother. But yes, Nunnally did confess her love to Rai in that ending.

i first read about this on wikipedia... i was sure it had said that lelouch AND suzaku tagged along on that date......

i am so damn sure Lelouch does not approve
