Can't You Just Let Me Be the Second Person If You Wear It Quickly?

Bai Yu, who was walking on the street, encountered a thunderstorm for the first time, and encountered a rare ball lightning, and then he couldn't escape, so he ended up being bound to the system inexplicably, and started to travel through various worlds inexplicably. That was all, but why couldn't he be allowed to be a human being if he was either a cat, a dog, or other non-human beings? Just when Bai Yu had accepted the fact and experienced the joy of being a non-human being, she discovered that she would always have a lot of love. (This time the author will try a different kind of entanglement in some stories, so it may cause controversy. Readers who don't like it can turn around and leave. If you think there are few chapters, or can't wait but like to read it, you can keep it on your bookshelf for now. I hope you will support me.)
