#3 - Bakemonogatari
#3 - Araragi and Senjougahara
I love these two for how unconventional they are. Her harsh personality has only come about from the trouble that the Crab had caused her and Araragi sees that. He also very obviously doesn't mind being led which is probably why he isn't drawn to Hanekawa. They both love each other's attention; Araragi loves that she leads and Senjougahara loves that he doesn't try to change her rough personality; she tries to do that on her own.
