What does Janie mean?

Is the heroine in the work "Mourning".

Ni Jia is the heroine in the work "Regret for the Past". It's cold outside and hot inside. I can't study well, but I'm surprisingly good at sports, especially long-distance running.

Ni Jia's work "Regret for the Past" tells the story that Ni Jia and Chen Jinsheng love each other but are heartbroken. The characters are plump and three-dimensional and full of personality.
