Both FLs are from the real world and in a historical game where they must complete tasks in order to return home again.

Both have a real world FL entering a historical setting game world and falling in love with the emperor ML who is a fictional character in that world. Both FLs complete the game and return to the real world, but out of love for the ML they choose to return to the game and spend their lives with him.

Both have a real life FL entering a game world set in historical times and falling in love with the royal ML who is a fictional character in that world.

Both are short length dramas with a real world FL entering a fictional historical world and unexpectedly falling in love with the emperor ML who is the main character in the world. Both MLs have invulnerability of a sort (plot armor as the main character vs. an immortal body) that leaves toward the end as the FL messes with the plot. Both dramas have a guide who gives tasks to the FL and only she is aware of/can see.

Both are short dramas in which a real world FL enters a fictional historical game world in which she must complete tasks to return home. The ML is the emperor and one of the tasks is becoming his queen.

Both are short dramas with the same actor as the ML. In both, the upbeat and cheerful FL is from the real world and enters a fictional historical world (game vs. drama). The ML is the emperor and the fictional main character of the world. Both have main characters (ML vs. FL) who are nonchalant about dying (FL dies over and over and the ML is immortal and jokes around with fatal things). Both have scenes toward the end in which the FL disappears in the ML's arms, returning to the real world, but both couples reunite at the end.

In both the ML swaps bodies (with the FL vs. his sister) resulting in positive character growth and some humorous moments.

Both have the ML and FL who lead very different lives accidentally body swapping due to some natural event (eclipse vs. lightning) and undergoing character growth as a result of the swap.

Both have family members accidentally body swapping (grandmother to grandson vs. brother to sister) with the male friend of the ML being the first person to know about it. In both, the body swapping leads to character growth/lessons for the ML.

While very different in tone and plot both have the ML and FL swapping bodies, leading to some very funny moments.

Both MLs have had their emotions or senses removed and the FL is the only one able to restore or give them emotions or senses again.

Both are lighter, shorter length dramas in which the main female character can read minds/hear thoughts.
