In the past timeline, after we defeated the shogun, she became the next ruler of the Kamikaze Continent. Due to the shogun's previous actions of killing the potential rulers that might usurp his ruling, Kamikaze Continent ended up losing all the people who are in the knows of the ruling. And since the only one who was left behind who knows much of the situation and ultimately the key factor to the shogun's ultimate defeat was his wife, the decision was entirely decided after that.
But right now, things have changed and I didn't even manage to do what I planned to do. The things I have cooked might not be wasted but I made a lot of it just so I can persuade her to join the faction of the rebels later only to see this twist of a development. Did I perhaps screw up the storyline in the past?
NO.
