The storyplot of FL being able to transport into a parallel world from contemporary to dynasty era and vice versa. Same goes with the ML, from dynasty to contemporary era.
The romance is almost the same...and yes, the fish kisses are just the same too. ?
Both dramas are entertainingly good. Even the humor are onpoint.

Same genre. Both FL are into sexual partner app search. But, I think Hit the Spot presented it better. ?

Both MLs have sleeping disorder and both remedy for their sleeping problem is the FL. Of course, both stories will end up with their respective partners.

Story plot is almost the same. Highly skilled FL became a full time housewife decides to re enter workforce. Alliance though has less toxic vibe compared to the latter drama mentioned.

Another drama that I keep on being reminded of while watching this drama. Same as Strong Woman Dobong Soon, the crime concept is almost the same. Serial killer of women that is traced back up to the present times. And yeah, the fantasy element of the ML being the police assigned to solve the crime in a timelined manner. Like, the ML from the past and present is the same.

The kidnapping crime relating to 7 deadly sins has almost the same concept in terms of story. And yeah, both of them has the same genre of fantasy and romcoms.

Same plot. Writer went into the book that she's writing. Same concept of romance novel with an overbearing CEO as ML.

Same ML. First time to watch him in this drama. You might want to check him out here, though I think the acting is almost the same.

Almost same story plot. Writer of the book goes into the book world and got herself involved in the story.

Both genres tackles about realities of marriage. Main Couple almost have the same character wherein FL wants to be a full time career woman while they both married an IT guy.

FL here have well off bestfriends who's there for her most of her down times same goes with TCAM, FL has a rich bestfriend who's always there to the rescue for her.

Both dramas tackles issues on infidelity, however, it is not much emphasized here compared to TCAM which is the main concern of the drama.

Both dramas story plot evolved in finding a cure for cancer.

Almost have the same finale presentation where there's a bomb explosion and survival training done by the MC that was applied towards the end.

Has almost similar plot of having a secret child. Both child actors in both dramas are adorable.

The differences...this one is a short mini series while the latter is a full length drama.
This one has fiery kisses ? while the kiss meter on the latter is as low as below freezing ?
