This drama understands exactly what it's about.
I was wary of the parallel storylines before I watched this drama. I liked the idea of them, but I was worried that they would be messy/confusing. They weren't at all! It was always clear which storyline we were watching, and the transitions between them were pretty smooth. I particularly liked the times when the storylines converged.

Overall, it's worth the watch if you like slice-of-life dramas and want a twist. It's also short, which is a plus.
