"What am I?" The questions that arose when I entered adolescence grew bigger and bigger, and I began to become interested in the reasons for human existence.After all, no one knew the truth about what this world was, and I felt that it was being sorted out by "changing according to people's beliefs and worldviews."
I want people who look for meaning in life, who have loved ones, and who like philosophy like me to listen to this song.
