This song is a sequel to "Post-Teenager," a song that expressed a sense of crisis among the generation known as "youth" about being replaced by even younger generations. The songwriter is from Generation Z, but vaguely felt fear about the arrival of the next generation, Generation Alpha, and regret for not having become a more accomplished person himself. However, without being caught up in vague anxiety, he also wanted to think about what he wanted to do and to achieve it in cooperation with others. This song, sung by two singers, features Megurine Luka singing for the first time in a while (she is not necessarily representative of Generation Z, but was chosen for her older image). Furthermore, it is the first time that Ui have been used in a released song.
