Reception
In April 2018, it was reported that the novels had more than 1.4 million copies in print in Japan.
The anime adaptation has often been criticized by Western viewers for perceived queerbaiting with regards to the relationship between lead characters Kumiko Oumae and Reina Kousaka, often involving significant homoerotic rewriting of the originally heterosexual scenes of the original novel series. Crunchyroll's Twitter account acknowledged the pairing by tweeting a screenshot from the show, which was still airing and being officially simulcast by the service at the time, in the wake of the legalization of same-sex marriage in the United States. The adaptation's director and showrunner, Naoko Yamada, has either denied any intention of depicting romance in some instances or expressed a desire to allow the audience themselves to determine the nature of the characters' relationships in others.
In 2015, Nio Nakatani praised the anime for its perceived yuri aspects, which she said had inspired her while she was drawing Bloom Into You. According to her, the first season of the anime "created the yuri that she wanted to write before she did" and she was so excited about the show that she started drawing yuri under its influence before she even realized that it "had a lot of yuri elements."
