The title track is positioned as the ending theme for the Nippon TV nationwide network TV anime "Ascendance of a Bookworm" Season 4, and this album includes songs that carefully portray true-to-life love as the theme, daily doubts and wavering feelings, and thoughts moving toward the future, with a focus on piano-centered sound.
