The cold and arrogant young lady, in order to avoid family political marriage, uses the "time loop" ability that fell from the sky to conduct a love simulation. But the cycle only lasts for three days, and after it is reset, the male characters targeted by her will retain the "afterimage memory" of the previous round. Kaguya has to go through cycles again and again, dealing with "test boyfriends" who are getting more and more understanding of herself and becoming more and more difficult to deal with.
