Both plots center around being inside a game. Their skills, talents etc are greatly utilized (to the point where it was getting a bit annoying).

...............................................

The two enter a game world and get involved with the protagonist......................................

Both are dramas about a real world FL who enters the world of a historical game/VR where they find true love.

VR romance genre with good emotional growth and throughlines. I would say Sassy Beauty have the stronger serious plot though compared to Love & The Emperor.

Both FLs come from the modern day real world into a historical world where they at one point are a servant, and at another pose as a man/are in a man's body. Both MLs are emperors who fall deeply in love with the FL, but realize she must return to the real world.

Both have a modern day FL traveling to a historical setting with VR/game elements. Both MLs are royal, and much of the story is set in the palace.

The two talk about a girl who enters a game to find true love....................................................

Both are love stories between a ruler and his servant. Both FLs are considered unlikely love interests (disguised as a male vs. a "plain" maid).
