Japanese stories are known for their explicit display of that mundane culture and turn it to something meaningful and beautiful. In this drama, it was centered upon the art of making traditional sweets called "wagashi".
The culture of wagashi is an interesting genre to explore for me, since I'm foreign to it. It was particularly catching to me since the characters show deep entanglement with that mundane culture. Its just about making sweets, but why does it feel so twisted and complicated? I just love it when Japanese writers do that.
Its something so simple...characters show varied emotions, thoughts, ideas, and eccentricities that were somehow revolving around the story yet those building emotions felt very central to that culture which makes it very complicated. You would want to make your way through the story because you get entangled as well. It catches you with your emotions as well.
I also commend the actors and actresses in this drama. The main leads did a very good job and this is the first time I have seen them. I love their chemistry. The main lead would likely end up to be one of my favorite Japanese actor!
Overall, if you plan to watch this drama, you are in for a treat! literally! and you might want to do a little research on the wagashi culture. When you understand how significant this culture is, you might find this drama more interesting!
