## Reception

The series both the anime and manga adaptation as well as the light novel received mixed reviews from various critics.
Caitlin Moore wrote that the anime is somehow both "ambitious" and "completely lacking in ambition". She noted that the concepts are "nice on paper", but the execution was "lacking", noting that both Ryuto and Runa have a "personality of wallpaper paste". She adds that the series is openly about sex. Still, the protagonists have "very little chemistry outside of a couple of scenes" and writers try to "inject some tawdry drama" by inserting a love triangle between Runa and Maria. She concluded that the anime was "fine".
Sean Gaffney of A Case Suitable for Treatment praises the first volume of the light novel for sticking to its theme of "slut-shaming is bad” but noted that the couple's progression is the "least interesting part of the series so far" noting that "Just because you’re not having sex doesn’t mean that hand-holding should take 60 pages."
