I am the promised wife of victory! “Sorry. I can’t answer your feelings for me.” The person I had a crush on ended up in the same class as me, and I confessed my feelings to her in a burst of happiness, but was naturally rejected. When I came home with such a low point in my life, the person who greeted me was… The person who was supposed to have rejected me just a few minutes ago, Himegi Touka, is that person! But she looked a bit older and sexier, and for some reason she was also wearing a wedding dress… Apparently, Himegi herself is from six years in the future, and she claims to be married with me there, and she seems to have a purpose. A life of cohabitation begins in order to happily marry the person who broke his heart in the future!
