Centimeter (センチメートル) in "Junjou cm" is word play for sentimental (センチメンタル), as the song is a sentimental ballad about the delicate sense of distance between the subject of the song and the classmate she has feelings for. This word play can be seen in the song's second chorus.
The music video for "Kon'ya Dake Ukaretakatta" was uploaded on YouTube at midnight between July 6 and July 7, 2018 in time for Tanabata, also known as the Star Festival, which is celebrated every July 7 in most of Japan.
For "Kon'ya Dake Ukaretakatta", the members wore yukata from the kimono chain store Suzunoya.
On July 13, 2018, Tsubaki Factory visited the Akagi Shrine in Tokyo to pray for the single's success.
