Ani ni Aisaresugite Komattemasu was serialized in the semi-monthly shōjo manga magazine Sho-Comi from June 21, 2015, to March 20, 2018.

To promote the live-action film, a television drama adaptation featuring the same cast was broadcast on Nippon TV from April 13, 2017,[a] to May 11, 2017.

High school student Setoka was adopted into the Tachibana family as a child, and despite only finding out recently, she still lives a peaceful life with them.

[1] In 2018, Yagami stated through an interview with Natalie that she felt the only way she could create a happy ending for Setoka and Haruka was for them to not be blood-related siblings.

[7] Yagami stated the fast pace of Ani ni Aisaresugite Komattemasu was partially due to the Sho-Comi being released on a semi-monthly basis.

[3] The film stars Generations from Exile Tribe member Ryota Katayose as Haruka, Tao Tsuchiya as Setoka, and Yudai Chiba as Takane.

[27] In addition, a special virtual reality video where the viewer can experience the events of the drama and film from Setoka's perspective was released on dTV on March 16, 2017.
