The Only You in The World (2021)

Both female leads can see the life clocks of everyone.
Have accepted fate to be as is no matter how much she tried to change it.

Both are short dramas in which the FL is a strong-willed, somewhat over-bearing CEO and the ML is a younger, sort of sweet and gentle man who she forms a contract relationship with (as a husband or assistant) for her own purposes. Despite one having fantasy elements, both dramas have a similar vibe.

the similarity between there dramas are
the ml/fl are suffering and the fl/ml are the only ones that can help

Similar Love Alarm 1 and 2 uses an app and The Only You has it above her head …………….…………….

Both are mini dramas in which the FL has some special ability causing a floating image above her or other's heads that only she can see.
