The female lead died and her heart was transplanted to another girl.

I recommend "The Forensic Detective's Little Wife: You're Arrested." This book tells the story of the protagonist being reborn into a little girl's body. At the same time, she has the ability to communicate with Yin and Yang. As a forensic doctor, she takes this opportunity to do her old job, fortune-telling and solving cases. The female protagonist of this novel was a slightly crazy forensic doctor. There were many suspense cases in the story, as well as romantic love lines. If you like forensic science (does it remind you of the female protagonist in the title when you see the sick female protagonist), and you like suspense puzzles and sweet love stories, then don't miss this novel. I hope you like this fairy's recommendation. Muah ~😗
