I've seen Narcissus which I thought was great. I have more requirements for Narcissus, the kind that I can tell at a glance that they are the same person really irritates me.
Soft science fiction, parallel world. The writing is very good. The few words at the beginning create a clear picture of the world in my mind. Every character has full flesh and blood.
Parallel world, the world view is well described, and the image of each supporting character is also very full. The only regret is that there are few posts.
The proportion is limited and cannot be five stars.
