The year Ran Mouri turned seventeen, a boy with glasses moved into her home. From then on, Ran's life became a happy (chaotic), joyful (a mess), delightful (explosive) adventure.
Before she turned seventeen, Ran had never doubted that she was an ordinary person. But when a boy moved into her home that year, she suddenly realized that the people around her were a little abnormal.
Oh, no. More accurately, there was the child prodigy with glasses, the cool, quiet girl with short brown hair, and, oh right, there was also herself, who could swap souls with people by shaking hands ever since the boy with glasses showed up, experiencing different lives. And those were just a few of the many people with stories of their own.
(Please note: When the female lead swaps souls with someone, she enters the version of herself in that person's memories and experiences their growth, emotions, and experiences. Meanwhile, the person whose soul was swapped out watches Ran's memories from ages five to ten like a series of fleeting scenes. People whose bodies are young temporarily lose their memories. Ran herself continues to grow and change through the soul-swapping process.)
