She is a time-traveling girl. In her previous life, she was a wealthy lady - Ji Qianjing. Once she time-traveled to the world of Detective Conan, she integrated into the protagonist's life and became Hua Yelan.
How can I put it this way? This heroine has a confused personality and a poor sense of direction. She can't find the road even if she holds a map. Even if you tell her to walk a few steps and then turn left and then right, she will definitely go wrong after walking three kilometers. The body shape is round, because I prefer girls with a curvy body (even though I am one), so it doesn't give people an abrupt and sharp look.
