I want to write a novel about time travel. The heroine is a cat-like woman, smart and naughty, with a pair of spiritual eyes. A bit cunning, but also extremely lazy. The male protagonist is a bit evil and a bit sinister. Occasionally he teases the heroine naughtily. They don't have to fall in love at first sight, but they do have to be interested in each other. In the fun and struggle again and again, they fell in love and stayed together until death, and they joined hands for a lifetime.
