Thanks so much for your kind comment! As someone with a lot of social anxiety myself, I was drawing on a lot of personal feelings for chapter four, so I'm glad it resonated with you.
As for the possibility of a sequel or additional chapters: yes, I would love to write more! If inspiration strikes, then future stories about Penny and Indira will end up here, or on my personal website.
In the meantime, you might enjoy a collection of short stories I wrote called The Bell & Other Stories: https://samlewis.org/stories/thebell/
