Youth Without Wind and Waves

My youth is without wind and waves. They all said that I was just an ordinary high school student, decadent, withdrawn, and not interested in anything. Until that mixed-race girl who claimed to have been reborn more than a thousand times came to me and told me the truth about the "experimental subject". Until I discovered that I could travel through different worlds and times in my dreams, and meet those regretful, crazy, and ruthless "me". Until my best friend closed his eyes forever in front of me. It turns out that beneath the peaceful campus life lies a past of human experimentation and an attempt to plan the future for all of us. And I must be between the tragedy that started on a rainy night, the despair of countless reincarnations, and the three transformed lives, I personally found an answer for this worthless youth that is more important than anything else.
