Hello, I am new here. I am unsure if this is the right way to do things.

I watched a short video on Facebook, seems like a C-drama, but there was no title. Now, I cannot find the drama. I tried searching for different possible key words to find it, but have been unsuccessful to-date. Could anyone help me?  

The scene I watched showed a grandpa entering an elevator.

An arrogant lady enters and the elevator becomes overloaded. She pushes the old man off the elevator and one of the ladies inside the elevator defended the old man.

The grandpa turns out to be the CEO/chairman's grandpa.

The lady who helped the grandma was applying for a job at the company.

The arrogant lady was the interviewer and threw her out.

The CEO hired the kind lady. 

This involves a fake marriage as well.

Thank you for your help.
