Mein Herz ist vom Umtausch ausgeschlossen

The book manages to be both funny and touching, which isn't easy to pull off. I'm curious about how the author approached blending these tones seamlessly.

The friendships seem so genuine and nuanced. What experiences or observations do you think influenced their realistic dynamics?

The city feels like a character itself, adding vibrancy and context to the story. I wonder if the author based it on a real place or created it from imagination.
