The official X/Twitter account for the live-action film of Minami Mizuno’s Koi o Shiranai Boku-tachi wa (We Who Know Nothing of Love) manga revealed on Friday that Rio Komiya will join the cast as Takahiro Kamijo, Koharu’s upperclassman.
The manga inspired a drama CD that Shueisha bundled with a limited edition of the seventh volume in October 2014.
The story centers on Eiji and Naohiko, two high school students who have been friends since middle school.
The manga began with a one-shot in Shueisha’s Bessatsu Margaret magazine in January 2017, before launching a full serialization in June 2017.
