She is actually the person with the strongest form of protection (boon), the one to change her destiny… Reborn in her favorite game!
Reincarnated as the villain in a world where everyone has blessings, Selisena herself has none.
Though the prince, her fiance , vouches to protect her, Selisena knows he is bound to break their wedding promise and marry the game's heroine.
And if the prince and the Heroine don't get to the happy ending of the game, she herself will be executed. (Otherwise, she'll just be exiled.)
So she leaves the prince in the heroine's care and goes on to look for her own happiness in this new life.
And in order to do so, she borrows land from her father and becomes a landlord.
