Chiyoko Fujikawa, the eldest daughter, is a woman of principle. Whenever asked to take care of a family member or a client at work, she always puts the other person’s feelings before her own and ends up losing money. One day, she was asked by her family to go on a blind date to find a partner to marry. The one who showed up was Ichijou, the “righteous man” she met on the way…?! She often fights with Ichijou, who is too frank and rude. She unconsciously gets mad and says many things to him, but for some reason… he likes it?
