Both dramas are essentially 2020s reimaginings of "old" romcom tropes from 2010s and both dramas execute use of these tropes well.

In both stories male CEO decides to enter a contract relationship with troublemaking female lead just to please his beloved grandfather (and essentially inherit the grandfathers company). The grandfather is in both dramas a goofy guy who knows more than he shows.

Both female leads are hardworking independent girls skilled in their own thing but sometimes helpless in male leads rich world of ritchy ritches.

Both drama have elements of slapstick comedy and animated way of expressing comedy.

The difference is in framing of the story - in TSOPMC, the female lead (joseon lady) time-travels from Joseon era into current time thus not being aware of modern customs; in ABP, the female lead is employee in ml's company and disguises as someone else to contract date the male lead.

The set up shares many similarities

- in both dramas, the female lead transmigrates into past (TTEOTM) or historical fiction (TROTaR)

- the female lead is in a loveless marriage with male lead
- the male lead seems to have feelings for older sister of female lead (TTEOTM) or female lead tries to set them up (TROTAR)
- the male lead appears weak and docile

However, the vibes of both dramas are different - Tiger and Rose is very comedy centered while TTEOTM (while still not the most serious ever) has more some more somber themes and the stakes of the whole story seem to be higher
