The cycle of cause and effect, the movement of the world, and human survival all run through cause and effect, because greed, resentment, regret, injustice, and great love prompt different people to take different paths, ultimately causing the collapse of the small world. Lin Shuxia, a debt-ridden high school student, travels through different worlds and strives to correct the life direction of the biggest villain, only to find that he has become everyone's favorite.
Villain: "You said you wanted to be my best friend, and good friends should always be together."
Everyone: "We will always believe in you, you are our faith."
"You love this true love in the world, so we will protect this love and wait for your return."
