Both these dramas tinker with the concept of time and how that affects the actions of a person, including the biggest question of whether destiny can be changed, though the elements of time travel are more explicit in AALS than SoT. More importantly, they also both have really strong, decisive, and badass FLs who have "soft" and "star-crossed MLs to support them.

Both of these dramas have strong and decisive female leads. The FLs are also unconventional, and the story does explore some philosophical topics in the morally grey areas of how life is structured.
