In every world, the protagonist has a disability. Life is difficult, but not tragic.
A different world means a different life. If you live in this body, you must do right by this identity. How can you be a clone of someone else's life?
Each world has a different environment and the protagonist has a different identity, so naturally they pursue different things in life.
These are the pursuits of the self in different worlds, not tasks to complete.
A serious story, with occasional self-amused quips. No golden finger.
Generally no CP, unless the world’s story calls for it.
The protagonist's gender is uncertain and changes according to their identity in each world.
Reality often surprises us. Perhaps the ending will, too. Take it as you will; each reader knows the warmth and cold for themselves. Is it joy or regret, success or failure? Readers can judge for themselves.
