Fate beyond Script

Both:
-have FL working against their 'destinies'. FBS in a scripted false world breaking a 4th wall and TDOL is working against fate after an unjust death caused by association.
-have FL who have regressed or started over multiple times
-have ML that are initially cold but then obsess over FL
-take place with a battle for succession going on in the background, both ML are involved in it
-have a similar comedic feel or energy and melodramatic side
-are 'short format' with 24 or so ep

Fighting against fate and what their character is supposed to do and be. Its a much better show overall.

Both have to do with a comic world and the characters trying to fight against what's been written for them.

Both are mini dramas in which the FL learns she is a doomed character in a fictional historical novel or manga. Both FLs then become determined to fight their fate, the original FL of the story, and the writer. Both MLs are villains/morally gray characters.

Both:
-Take place in a book or alternate reality & have FL that are aware of this
-FL want to change their fates
-FL are both originally cannon fodder. FBS is a dead wife whereas LGEF is dead wife and villainess.
-ML are initially cold and cruel and loved someone else first but become devoted to FL.
-ML have longer hair and were both considered villains in their original plots

LGEF takes place in a supernatural martial based world whereas FBS is more court intrigue palace based with no supernatural plots besides fate. LGEF is way more comedy+drama based and FBS is more drama based.
LGEF FL is more bubbly or annoying whereas FBS is more poised and calculating.
LGEF is long format and FBS is short. LGEF is NOT at all as steamy.
