I'm amazed by the plot. The drama gave an insight into the top 1% making decision. There are many plots like this but not with a clear aim like this drama.
Grandson and grandfather were persistent and ruthless in competing with each other for their own goal making you unable to stop watching. Truly. I thought it was always about business between them but there was emotion. Despite all that, he still wants his acknowledgment.
I watched their BTS, actors delivered their characters very well. SJK is a good actor but I'm contemplating specifically when do-jun flustered, he covered his mouth with hand, and his emotions at that time look awkward or it was intentional? Above all, I respect and praise harabeoji, Lee Sung Min's acting. Of course, salute to the production team.
I recommend this drama and watch how they utilize historical events as their business plan.
