Yup I definitely agree with you! The mc isn’t dumb or clueless at all. It’s completely understandable with how she is acting because she only read a novel about Ains and she probably didn’t get very far in the story (idk if she really did this is just a prediction) before she was teleported into that world. The mc believes that Ains is a pure and innocent boy but soon she is gonna see his true colors.
I'm at Chapter 20 and I can tell you that nope she still is clueless LOL

A lot of people are angry at the mc because they think she is stupid and clueless, but we are only at chapter 10, i think there's still time for the plot and characters to grow. At least i hope so
