maybe it's just me reading to much in to it, but it seems like Eunice in the last 2 or so chapters has shown great character growth, she clearly takes great pride in herself and what she has accomplished under the MC's guidance and seek recognition from her teacher, the MC, she is also very clearly highly gratefull toward him for sticking to it and teaching her despite her earlier behavior, it is also clear as day she lacks the social skills to clearly communicate these feelings toward him, her telling the story of how they beat the dragon in what seems to be very intricate detail is her looking for his input on her performance. all this hate she recieves is seriously undeserved.
the only annoying thing here is you haters.
