Both these dramas begin in the same way. The main male character falls in love with a simple girl, who is the heir to his business empire. Difference between rich and poor. The boy's family does not accept the girl. But the boy always stands with her.

The female leads have two personalities in both the drama, one is bold other is shy. its really fun to watch.

both have a connection to the female lead

#incarnation

#deity/immortal

#sense of love is sealed

#love triangle

Both the lead actresses have some other life fantasy, and they get something else out of life. The inner court, society, family, and war field is a journey of thinking to establish a balanced state by passing/opposing all these. There are similarities in the story, I will not spoil the story by telling those similarities

*both the female lead has a special power
*both male lead and female lead are the cop
*initially both leads have trust issues and conflict
*the cause of conflict is the male lead loved one died and the female lead is suspicious according to the male lead
*afterward, they work as a team to solve the case
*serial killer concept

they try the same illusion kind of concept in both dramas so the audience can amages it.
one is about gaming where they not met in person but connected by game and game character played by themselves other drama main element is a dream they didn't meet in person but the in the dream it has already.

1) At the beginning of both the dramas, you will see that one artist has a one-sided love for another artist, and s/he loves him/her from a distance.

2) In the middle you will see that in both the dramas, both the actors will fall in love with each other in a dream world.

completely same story

Both the dramas start from the same point, after killing the royal king father, the uncle takes the throne, in his unsuccessful attempt to kill the princess gets injured and hides for a long time and waits for the right time to take revenge. both female leads are intelligent to tackle situations.

both dramas are about time/incident loop where the looping process happens to be the only main protogonist and they try to save their loved one and themselves from that disaster.
