Everyone knows that every book has a male supporting character who loves someone he can never have. After evolving a deep-love trait, he gets targeted by evil spirits and always dies halfway through the story, never making it to the end.
Ran Qiqi, a Host who is a permanent fixture in the black-room world, gets kicked by the Bureau Director into a world where she has to protect male supporting characters.
Ran Qiqi: Sorry, I only know how to kill people. I don’t know how to protect them.
System: ...Heh. Could you at least stop tormenting all us single people?
