This is just an effort to document and put together all the fan noticed-subtle details/gems found in the drama. 

Non of the below details or observations are mine. Credit goes to their OG creators/detectives. As a loyal and addicted fan of this drama, I just want to document all this gasping information in one place and make note. Again, I am making this public so you all can also add to this and we can share these interesting nuances and hidden information. 


Feel free to comment or reply to add to this list :)


  • After Paek Sa Eon saw Hong Hee Joo's car damaged (fender bender + hacking) in ep2, he gets her a new car. We see a switch from KIA in ep2 to BMW in ep3.

  • The white heels Hee Joo wears during the railing scene. As she approaches the elevator to leave, you can see her wearing her backstage/bts brown sandals instead. lol.

  • To Sa Eon, "sunset" symbolises Hee Joo (hence his wallpaper is sunset). With this meaning in mind, he was scared that a complete sunset would mean he would loose Hee Joo forever in ep6. So the moment the portable flare lit up in the darkness, he ran towards it like nothing else mattered and as if it was his only hope that was ignited. To find her and to be able to see his sun rise again. The flare represents a spark of hope to find her.

  • He treats her like a princess and provides for her the best. Her bedroom vs his, her bed vs his, her bathroom vs his, her car vs his, and her wardrobe.

  • The dog in ep8 is Sa Eon/ Yoo Yeon Seok's real pet named, "Rita".

  • The reason Sa Eon took a victory photo with Hee Joo in their retreat was because he saw Mr.Kang's phone's home screen wallpaper (him and his wife happily eating ice cream) during the bus ride scene in ep7.

  • Although Sa Eon's wedding ring got more screen time than Hee Joo's here's what they each mean: His ring signifies to be lovers sharing a ‘Tilted Umbrella’. Tilting an umbrella means to protect a beloved from the rain, letting one’s own shoulder bear the storm. Sa Eon’s silent and quiet promise to shield Hee Joo from every raindrop. Her ring signifies "One Love" and symbolises "Pure Love" that keeps only one partner by its side for a lifetime and it is shaped like a goose.
