Yoshitaka plays the heroine Kamata Rinko, a scriptwriter in her 30s who is facing a bottleneck at work and has no boyfriend. She spends her nights having girls-only gatherings with her buddy Yamakawa Kaori (Eikura) since their senior high school days at an izakaya named Nonbee while lamenting about the "what ifs" in her life and how things will turn out better if certain things or conditions are fulfilled. For example, if she is prettier, she would be able to find a good man. If she falls in love with someone, she would be able to get married. If she puts in effort, she can get anything she wants in her life. All of a sudden, she realises that she still hasn't matured as a woman despite having entered her 30s as she reflects on her inadequacies. Kaori works as a nail artist while Oshima plays Torii Koyuki who works at Nonbee. Sakaguchi plays the role of KEY, a famous and charismatic model who tries to knock some sense into the girls and Suzuki plays Hayasaka Tetsuro who is a drama producer and was dumped by Rinko in the past.
When asked to describe her character, Eikura who is appearing in her first drama since getting married to Kaku Kento in August this year, described Kaori as a free spirit who tries her best but ends up running around for no reason so she hopes to make her character interesting and relatable to the viewers. As for Oshima, she said that the manga seemed to be talking about how she truly feels as a woman around the age of 30 and she hopes to show the positivity of life through her character despite the challenges the three women face in their lives.
