A high school sophomore transmigrates, only to be exploited by a heartless System.

System: Host, complete your mission and you can return to your original world.

Ling Yue: ? What if I don't?

System: The Host will remain in this world forever. The System may stop your bodily functions at any time.

After completing the mission

Ling Yue: System, send me back.

System (still playing dead)

Ling Yue: ...!!!
