Wotakoi: Love is Hard for Otaku final chapter is coming out on July 16th, with the final volume out on October 14th, 2021. The special edition of the final volume will come bundled with a new OAD episode.
The new episode will adapt the “Employee Trip Times” story from the 6th volume. Studio Lapintrack is producing the OAD (original animation disc). They also animated the previous Wotakoi OAD (bundled with 10th volume).
Wotakoi: Love is Hard for Otaku manga first started publishing in 2014. It received an anime adaptation by A-1 Pictures in 2018. In addition to the OADs mentioned, the franchise also has a side-story OVA from 2019, which is titled Wotakoi: Love is Hard for Otaku – Youth.
Kodansha licensed the manga for the English market and describes the plot as:
Narumi Momose has had it rough: every boyfriend she’s had dumped her once they found out she was an otaku, so she’s gone to great lengths to hide it. When a chance meeting at her new job with childhood friend, fellow otaku, and now coworker Hirotaka Nifuji almost gets her secret outed at work, she comes up with a plan to make sure he never speaks up.
But he comes up with a counter-proposal: why doesn’t she just date him instead? In love, there are no save points.
