Principal photography for the first season took place in 2021.[1]


The series received mixed-to-positive reviews. Praise was aimed at the performances from the two leads and the progressive commentary the series presented. However, there was some criticism aimed at the inconsistent tone and lack of any real stakes.[11][12][13][14] The series was review bombed on IMDb with many misinterpreting the series as being about a transsexual character. Despite implications, the series makes no mention or reference to any LGBTQ+ topics.


Eri Sakai has expressed interest in a follow up season that adapted Childcare Edition.[15] However as of January 2024, no confirmation has been made about a season 2. Sakai has also expressed interest in a Korean remake and anime adaptation of her manga.[16][17]
