This is probably one of the series where value dissonance strikes hard, because I find It difficult to agree that the protagonists' relationship should be seen as an affair and Ririko is a thief just because Kyuuta was in an arranged engagement he knew nothing about and never wanted.
Other than that, the manga wasn't bad and the ending was nice.
1) Page 6, that's a reality folks, women flocks around successful man.
2) Page 15, Reidou, the exact definition of a feminist, blame all men for the fault of one man.
Late reply since I only found out about this manga. I am so glad the two of them got a happy ending and everybody accepted them and they even have a son together.
