Rather than reject Nagisa outright or break up with Saki, Naoya proposes that he, Nagisa, and Saki all enter into a three-way romantic relationship, and hijinks ensue.
Kanojo mo Kanojo follows the romantic adventures of Naoya Mukai, a first year high school student who is serious but indecisive.
The Kanojo mo Kanojo TV anime is scheduled to begin broadcasting in Japan in 2021.
