[KeitaroNagato]

At least I understand Minorin does have some feeling for him, and understands that he feels the same way. Yet, is it not part of the growing social structure to go after what one feels it's for the best, regardless if Taiga is in the picture. I've always thought in sense of pursuing what was impossible to reach, it is now tangible, the opportunity to grab for. Is that not part of social conscious in cultural sense?
I do understand Minorin reaction towards Ryuuji, but the opportunity presents itself, and she is "contracting" herself.
The fact is her "ghost", is right there. Thus, she does not want to acknowledge it. In other words, "avoid it completely".
