One Two Three, Mu Tou Ren (2022)

I think both dramas are similar in few aspects:
1. FL has terminal illness
2. ML and FL have a contract in the beginning but fall in love later on.
3. ML is supportive of FL, when learns about the illness
4. The ending is also similar - Being Positive

I don’t know why they just remind me out each other and they are both really good.

Both dramas have the fl being ill/sick
However, Smile to Life doesn't have any of the leads being a doctor (the ml is a musician)

Both have a main lead that is ill/sick and they have ALS.
However, the female lead has ALS in Smile to Life while the male lead has it in this drama.

In both dramas :
- Sick Female Leads
- Famous lead - Common lead
- Melodrama
- Music
Are common...
Both dramas are heartwarming...

FL is sick in both dramas and is fighting for joy and happiness against life. Keeps the illness as secret.
FL breaks up with ML to not be a burden
FL is bubbly and energetic.

ML is a celebrity, a singer songwriter
FL is a regular person
Both shows deal with illness
In FP, ML's daughter has leukemia but in STL, FL has ALS
Both shows deals with scandal
In FP, FL is at her height in fame but temporarily brought down by scandal but in STL, ML is no longer popular and trying to work his way up back to fame but scandal is blocking him
Both shows ML and FL work together to cover up a lie/misconception

Synopsis ??????????????????????????????????????????????????????

The drama tells the story of how an ordinary girl Xia Guo chooses when faced with two different choices, and what happens. The drama is presented in parallel time and space. The different choices of the heroine will lead to different endings.There are the challenges and dilemmas of the big city; but on the other hand, there is the stability and triviality of the small town. In life it is always necessary to make concessions, without fear of loss, and moving forward to embrace that sense of the "extraordinary." If life could have other versions, and the "if" could be experienced, what would it look like? The drama realizes this "if" so that the heroine experiences two lives in parallel. How she will handle those choices is the big question.

"I live elsewhere" (from original title in chinese).
