On January 1, 2011, Wang Hao, a first-year high school student, accidentally sends a letter to another timeline.
She has spent years grieving the loss of her beloved. At a single glance, tears stream down her face.
Without hesitation, she becomes humanity's first volunteer in a parallel-universe experiment with an almost nonexistent success rate. By a twist of fate, she arrives in the world where he lives.
Worried that the boy before her is still far from the man she loved, she doesn't reveal who she is right away.
She is afraid that the butterfly effect could lead to unimaginable consequences, and she also wants to do everything she can to prevent the tragedy that left him with a lifetime of regret from happening again.
She knows that what determines who a person is isn't simply their DNA, but every choice they make of their own free will throughout their long life.
But as events unfold, she gradually realizes she isn't the only outsider in this world.
Absurd and bizarre, a kaleidoscope of strange sights.
Magical realism, chaos everywhere.
Rather than call it the real world, it would be more accurate to call it a metaverse.
Dangers come one after another, and doomsday follows close behind.
The young people, hearts full of passion, use their youthful spirit to save the world.
