Read the novel immediately after chapter 12 as at the time, it was not updated yet. Got impatient and read until the end of the novel. It was a good ending but one thing I have to say about the Bertia in the novel was that her idiocy was excessive. It ruined my impression of her a bit in the novel. However, coming back to read it with a doubtful mind of my past 5 star rating, Bertia is really loveable. It is well deserving if the rating. Other than that, it is not often do you see an isekai with a ML who is aware and furthermore in the POV of the male lead. Good manga.
