This song is about a dialogue between "myself" and the "other self" in my brain. The two talk about the loneliness that has been ingrained deep within their hearts. This work is a song that further deepens the resolution of the ``how to deal with loneliness'' that Too Aka often writes about. I hope it will reach people who are too demanding of perfection from themselves, people who can't rely on others, and people who are suffering in secret in the corners of their rooms. We aimed to create a sound that would be enjoyable even if you just follow the lyrics, and would be easy for people who normally listen to the song to focus on melody. Contrary to the philosophical theme, a warm atmosphere is created by the soft and broken word choice, the refreshing band sound, and the acoustic guitar that can be heard in between.
