Reception
For the live-action film adaptation, Mark Schilling from The Japan Times gave the film 2 out of 5 stars, stating his discomfort at Ayuha and Mr. Hiromitsu's relationship as student and teacher. In his review, he noted that student-teacher romances with dim-witted heroines were still vastly common in Japan compared to the West. He also stated that Ayuha's character was far more realistic in the manga than the film.
