Communication is a wonderful thing, but this dumb FL doesn't know that

I blame the ML. She has every reason to not trust people.

The only dumb thing is you. What's she supposed to communicate? She already communicated enough and can't reveal everything where it could put her life at risk. People like you always make it sound as if communication easy thing because you read the manhwa and know what's going on with both sides but never imagine yourself in one side without knowing what your partner thinks.
