The purpose of "I'm here too, alone." is to delve into an understanding of an existential dread or anxiety type situation, and not only to feel more comfortable with it and able to deal with it, but also explore it and find fun and creativity in it. The character that you *speak* to isn't anybody, and it isn't somebody, it's more your guide, or your understanding.
Hello! I'm the author of "I'm here too, alone." I do plan to work on more pieces after finishing this series but likely only after finishing the series.
