Thanks for the answer : ), maybe my translation was wrong or my expression was wrong. What I'm trying to convey is not that these things are useless, but that I found bugs (maybe?)at what time. I'm not stuck in a scene, I know where these props come in.
What I'm puzzled about is: seeing the MC's reaction I feel like she should have met Diana, but in my memory the MC never seemed to have touched Diana before, so I wondered if I missed a scene with her, or if Diana appeared early,
