The official website for the television anime of Tamiki Wakaki‘s 365 Days to the Wedding (Kekkon Surutte, Hontō Desu ka?: 365 Days to the Wedding) manga posted the anime’s third promotional video and second key visual on Saturday. The website and video announced three more cast members, and the video also previews the theme songs.

The newly announced cast members are:

The anime will star Saori Hayami as Rika Honjoji and Kentarō Kumagai as Takuya Ohara.

The cast also includes:

Hiroshi Ikehata (FLCL Progressive, Dark Gathering) is directing the anime at Ashi Production. Kazuho Hyodo (Kiratto Pri☆Chan, TONIKAWA: Over The Moon For You) is overseeing the series scripts, and Shuji Maruyama (Isekai Cheat Magician, Helck) is designing the characters. Shun Narita and Yūsuke Seo are composing the music at Pony Canyon. Ryōsuke Naya is the sound director at Studio Mausu.

Additional staff members include:

HoneyWorks feat. HaKoniwalily are performing the opening theme song “Kirakira” (Sparkling) and GOHOBI is performing the ending theme song “Tsumari wa” (In Short).

The anime will premiere on October 3.

Seven Seas licensed the manga, and it describes the story:

Takuya and Rika are coworkers in a travel agency in Tokyo. They’re both single, but they don’t mind, since they’re introverts with fulfilling lives at home. Unfortunately, now their job is looking to staff an office in Siberia, and non-married employees are the first to be considered. Rika is desperate to avoid the transfer and goes to Takuya with an idea: if they pretend they’re getting married in a year, they can stay in Tokyo. The only problem is the two of them barely know each other! If these two quiet coworkers “fake” a relationship, will it turn into something real?

Wakaki launched the manga in Shogakukan‘s Weekly Big Comic Spirits magazine in March 2020. The manga ended in its 11th volume in July 2023.

The manga inspired a live-action series adaptation that debuted in October 2022.
