Purgatory After a Forgetful Death

Your death was certainly tragic. With no memories, no one to say goodbye to, no secrets to take to the grave. All caused by the slow and horrifying deterioration of brain tissues. Strangely, you found yourself in a peculiar place after exhaling your last breath. A parallel-universe version of yourself, where you're a troubled Princess. You did remember bits of your past life, you remember being born biologically male, you remember how you died too. A deity left a ominous message for you, seemingly explaining that you will fully remember who you were if you 'win'. It also warned you not to die in this world.

As time passes by, you grew somewhat accustomed by this world, this purgatory. The other princes seem to develop a deep fondness for you. Maybe a little too deep, watch out for their words, their subtle actions, their deranged eyes and their gifts, then you might just understand what I meant.

Careful now, old man. One wrong move can give you memorable, but scarring death.
