The official website of And Yet, You Are So Sweet live-action film announced on Oct 5, 2022, that Riko has been cast to play Chika Obara, who is the best friend of the protagonist, Maaya.

A character visual as well as Riko’s comment regarding her role has also been revealed.

Comment:

Since many of the cast members were of the same age, it was a very enjoyable shoot. We had a lot of casual conversations between takes, and I am sure that the fun atmosphere was reflected in the film.
Obara, the girl I played, is the kind of girl who gets along with everyone and makes you wish you had a friend like her. She is a boyish girl, but I also wanted to express the kindness and dependability that I felt when I read the original story.
There are many scenes that will make you swoon, so I hope you enjoy them, but I also hope you will pay attention to the track scenes, as we all worked hard together as a track team.

It was previously revealed that the main characters Maaya Kisaragi will be played by Mei Hata and Sui Chigira will be played by Naniwa Danshi member Kyōhei Takahashi. Rihito Itagaki has been cast to play the role of Soma Tezuka.

The film will be directed by Takehiko Shinjō, with Haruka Okita serving as the scripwriter. The film will be distributed by Shochiku.

The film will release in Japan on March 3, 2023.

The official website describes the plot for And Yet, You Are So Sweet as:

Maaya (Meiku Hata) is a high school sophomore whose first confession of love in her life has been rejected.
When she is downhearted, she is seen by Chiki (Kyohei Takahashi), the ace of the track team and the most handsome boy in school. For some reason, Chikki-kun, who is popular with the ladies but is always salty toward those around him, proposes to Maaya that they play “one-sided love game”! He says, “Why don’t you have a crush on me instead of forcing yourself to find someone you like? The conditions for playing “kata-jo-yoso” were that she must never fall in love with him and that he must not find out about it. Although it is a promise not to fall in love, Maaya’s feelings are gradually shaken by her secret relationship with Chikki-kun, who is kind and too sweet only for her….
What are Chikki-kun’s true feelings for her? What will happen to their love…?
