The female protagonist is a bit silly, with a very strange brain circuit, while the male protagonist is beautiful and powerful, but he once felt low self-esteem because his tail was not good-looking. It's just a bit anticlimactic and the ending is sloppy.
It's a good interstellar novel, but I don't know why the score is so low. The heroine is a time travel, grassroots heroine, the kind of aristocrat with a bit of a philistine mentality, not noble, very down-to-earth, and very real.
The female protagonist is a nine-tailed cat demon who became a heavenly master after her soul passed through a human being. She has a strong sense of inhumanity and involves a real and fake daughter. The female protagonist is strong and the male is weak. The male protagonist is a bit redundant. An ordinary human with outstanding abilities has an unequal lifespan and ability. I feel that the male protagonist will eventually become a passer-by of the female protagonist for a long time.
