Contract Concubine - Chapter 29

The story is interesting but I’m getting annoyed at how sloppy she is. She literally is an terrible assassin when we are supposed believe she is so badass that her nickname is the grim reaper. Everyone is supposed to be suspicious and she doesn’t know who is the double agent spy is. But she readily tells him everything? Like so sloppy. Anyone could had seen her face while she was in the courtyard. Where is the story even going? She just straight up has plot armor at this point.
