Searching for a Korean drama. But I don't know what his name is.

There was a company owner who had two sons
The eldest son was very obedient.
The second son is very disobedient and does not know how to do anything
He didn't know why his father had kicked his second son out of the house.
And any credit cards on him were confiscated
The little gentleman came to a woman's house
Later, this man stole the woman's passbook and bought so many things back.
This man loved to call such women evil aunties.
I didn't really take a good look, that's all for now.
I watched it on Star TV.
