I watched five eps of this series and the premise was so ridiculous to begin with that it never really recovered from the implausibility of the storyline. An elderly lady loan shark who wanted to give her collaterals back to their owners.
By some silly implausible means a chicken bar owner and his family move into her palatial house - but she doesn't move out - the family are forbidden to go to the basement. A little later a young man also moves in - he is a failed entrepreneur who wants to make his app a start up business.
The elderly lady wants both men to track down the owners of the collateral and give them back. There is the usual threat to his chicken business by different competitors moving into his area - and his wife meets an old admirer. I could not maintain any interest in the boring plot - especially when some singer or other had to get in on the act. This happens a lot in Kdramas - actors who just have to be given a singing spot - usually in "let's go to a karaoke bar" incidents.
When I fell asleep for the third time I recognised defeat.
I gave up.
