I watched the drama in one sitting and often skipped due to unnecessary scenes.

Plot: I feel that the story is underdeveloped. It is complex but lacks depth. The story lacks a central conflict driving the narrative. There were plot holes, and the investigation of the death story was not seamlessly done. I always think it was added to complicate the story, but it's unnecessary. Indeed, the characters must be built out of circumstances that happened to each character, but the female lead character was full of twists, trying to make her life appear miserable and broken, and to me, ended up with a question - what happened?

What's good about the story: They were able to stitch a good story about the cause of divorce between HJ and LS.

Romance: I think it was sufficient; it was nicely done, and it did not feel like the story was trying so hard to build the romance. It was ok.

The title: It seems they made the title as if the trunk is the driver of the mystery, but it was disappointing... Is it just me? The trunk could even be omitted.

The acting: I liked Seo Hyun-jin even from the other dramas she did. I knew she was a good actress. I know that Gong Yoo was one of the most popular actors in Korea, but I've not seen his works, apart from the old Coffee Prince. Maybe he is a good actor, but I did not feel him in this drama.

Recommendation: Watch later when you have no other drama to watch.
