After graduating from college, Shen Siyue suddenly finds herself back in the summer after the college entrance examination. By accident, she gets a check-in system, and the system keeps insisting that it wants to give her a happy life.

But who can tell her why, when she was already ready to coast through life, she suddenly starts traveling from world to world instead?

World 1: Take it easy in a period novel with a tragic-background father.

World 2: Get a close-up look at the post-apocalyptic female lead's private life? No, no, it's just an immersive post-apocalyptic experience.

World 3: In the world of Empress Zhen Huan, she becomes Lin Daiyu's stepmother? This must be the world's problem.

World 4: A gorgeous vase type breaks free from her sugar daddy and charges into the entertainment industry? No, she is riding on the coattails of the reborn female lead from the original story. Wait, how did this transmigrated woman get involved?

World 5: Go to Detective Conan and Jujutsu Kaisen to do the things she's always regretted not doing.

World 6: A scheming white lotus? Run, run quickly. Wait, it's a revenge black lotus? Then that's fine.
