In every world, the protagonist has a disability, which is not easy, but not painful.
To change the world is to change a life. To live in this body, you must be worthy of this identity. How can you be a clone of other lives?
The environment of each world is different, the identity of the protagonist is different, and the things pursued in natural life are different.
It is the pursuit of self-life in different worlds, not the completion of the guiding task.
It's a serious drama, with occasional rants for self-entertainment, but no cheats.
Basically no CP, unless the world plot requires it.
The gender is uncertain, and the gender of the protagonist in each world changes according to the protagonist's identity.
Reality is often unexpected, and perhaps the outcome is too. Just look at the water and you will know whether it is warm or cold. Is it joy or sigh, success or failure? The judge will make his or her own judgment.
