Yay! I found a diary for Nunnally route in Ashford:
1st part,
2nd part,
3rd part.
This video guide should be helpful.
Ashford Chapter is so hard to understand. Last time I stick to Lelouch as much as I can, but still got Milley ending. This time I try to avoid Milley, but oftentimes I'm left with only Suzaku, Nina, and Shirley to talk to.
At this rate I'll end up kissing Nina, or with Shirley if lucky.
I understand about Shirley, since I chose to join the swimming club. (With the other two options being 1)"go home" club with Rivalz or 2)science club with Nina... that left me no choice.)
But why do Suzaku and Nina love me so much?
Lelouch, where are you? ;_;
