"Iris, I will dissolve our engagement." "---Yes, I'm glad." Thus, Iris, the wise princess, was freed from the chains of duty. With her newfound freedom, Iris encounters Alvin, the prince of a neighboring country. Upon meeting him, she regains her memories from her previous life and realizes that she has been reborn into her current self after traveling back in time. In her past life, she was Fiona, the sword princess and the next queen, who was Alvin's cousin. If things continue as they are, Fiona will be betrayed by the prince she admired, lose her position, and be exiled, ultimately meeting a tragic end. Determined to save her past self, Iris uses the knowledge and memories from her two lives to win the favor of Prince Alvin and secure the position of Fiona's tutor. She aims to change the doomed future by staying by Fiona's side. "You really do favor Fiona, don't you?" "Yes, so I don't have time to entertain you. And please don't touch my hair without permission." "Don't worry, your hair is so smooth." "We weren't talking about that!" This treacherous prince is a real nuisance. *This work is also posted on Kakuyomu. The web version is the original draft before the book version's revisions. The main plot is the same, but the web version has less of Alvin's tsundere qualities and some minor inconsistencies remain.
