Date no Hi wa Nido Kurai Shower Shite Dekaketai / Junjou cm / Kon'ya Dake Ukaretakatta (デートの日は二度くらいシャワーして出かけたい/純情cm/今夜だけ浮かれたかった; I Want to Shower Twice Before I Go Out on the Day of My Date / Innocent cm / I Wanted to Be Festive Just for Tonight) is Tsubaki Factory's 4th single. It was released on July 18, 2018 in 7 editions: 3 regular and 4 limited. The first press of the regular editions included a random trading card of 10 kinds depending on the jacket (30 in total). Limited Edition SP included an event lottery serial number card.
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.
