It Seems That I Have Been Reincarnated but Not Reincarnated Yet.

I was reincarnated into a different world due to an accident, but God seemed to have made a mistake, and she forgot about giving me a mission. After being reincarnated into a different world, I gradually discovered a sense of dissonance. Why was my experience in this life so similar to the previous one? Apart from mastering some abilities, was I really reincarnated? Taken together... It should be like this... This novel and its characters are purely fictitious. Any similarity is purely coincidental and should not be imitated.
