Tokyo: This narration is wrong!

Traveling through Tokyo, with a 30-year-old soul and an 18-year-old body, I thought I had made a profit until I got the diary of the original body and heard a strange narration in my ears...
[Tsk tsk, the kind-hearted wife, the cold and arrogant sister, the lonely top student, the intellectual big sister, the melancholy female writer, who will become the target of the diary owner? Or the hunter hiding in the dark waiting for the lost lamb to fall into the net? ]
This book is also known as "My Neighbors and Me"
