I'm going to write a novel, but it's not easy to name it. I'll recommend it. Because it's a sibling relationship, the male and female protagonists have the same surname, Leng.
The male protagonist had a cold personality. He would only act like that when he met the female protagonist. Of course, he would also act like that when he met someone who was close to the female protagonist. He wanted a three-word name, not a two-word name. He didn't want it to be vulgar. He wanted it to be noble and elegant. Moreover, he had to write a name that looked good and sounded good (I know the requirements are a little high).
The female lead was more cheerful and lively, but she was also cold when necessary. Her name was the same as the male lead's. It had to be three words, not two words. It didn't have to be vulgar, but noble and elegant. It had to be beautiful and pleasant to hear.
The female protagonist also had four pets. There were no requirements for the names. One was a wolf, one was a white tiger, one was a white Tibetan mastiff, and one was a white Ragdoll cat. There were no requirements for the names.
Next was the name of the novel. The novel was about a pair of siblings who had been reborn in the apocalypse. The female protagonist was reborn. After she was reborn, she had space and traveled around the world. She bought a lot of things. The male and female protagonists had extraordinary identities and created their own world in the apocalypse. However, this was a story for the future.
Remember, the name must not be used by others before, or else it won't be created.

Answer 1

The cold-blooded heroine is cold-hearted.

Coldblood and Leng Xin were both homonyms for the surname Leng. It was easy to read and did not have any negative meanings. These two names implied that both the male and female leads had a cold and ruthless side, but also had a soft and warm heart.

Cold-blooded and Cold Heart could be used not only as the names of novels but also as the names of characters to highlight their personalities. In a novel, the names of the male and female protagonists could be used to create a dramatic and emotional story.
