Both are short dramas in which a historical ML time travels to the present day and meets/falls in love with the FL.

Both are darker, more intricate historical dramas with a similar tone and pacing. In both the FL's is originally the king's bride, but circumstances and political scheming result in her leaving the palace/being presumed dead. Eventually years later, she returns to the palace and returns to her position as queen. The ML in both is struggling against powerful people in the palace, all while trying to protect the woman he loves. Both stories have shamans.

Very different in tone, but both have a ML who has a demon personality trapped inside him that is slowly taking him over. In both, most of the world wants to kill the ML to destroy the demon, but the FL is determined to save his human side.

Very different in tone and length, but the FL in both is able to summon the ML who is a supernatural being.

Both are short dramas that start out light and fluffy then get more serious toward the end. The ML has a more sinister, darker personality trapped inside him that is trying to take control and who the FL is trying to save him from. Both FLs are from modern day and have traveled back to ancient times where they met the ML. Both FLs have some form of magic and are connected to the ML in a supernatural way. The ending is open but the two reunite in some way in modern day.

Lighter tone, short, and enjoyable dramas with an adorable FL who travels from modern times to a historical setting, meets the ML and falls in love with him.

FL travels from modern day to historical setting, meets and falls in love with ML. Both are fluffy, light dramas with a quirky and adorable FL.

Historical set, breezy dramas. In both the ML has been poisoned (although it doesn't affect his health, only his senses in YSMD), and the FL is the only one who can ease or cure his condition which results in the two living/working together.
