I still don't understand how he manages to play hooky from the orchestra for two weeks a year without anyone making a fuss!

Yes, that issue was a bit fuzzy. But my impression was that his orchestra went to Switzerland every year especially for that event for young musicians organized by Yoon Se-ri's company. But how he manages to live with her for those two weeks, and not in a hotel under the supervision of some North Korean secrets service operative - I don't know. Maybe he has special privileges, because of his father. :)

And I glad you enjoyed the drama. It gave me a lot of joy and I'm happy I encouraged other people to watch it. :)
