Gunshi Kanbei - historical drama, a brilliant strategist in chaotic times...
Beethoven Virus - a conductor of classical music, one of my favourites
Surgeons - well, a surgeon... best one in the hospital, brought in from the US, looking for revenge for something that happened in that hospital when he was a child. The female lead is also very skilled, but he has more experienced and more level-headed and also good at other things like cooking and comforting little children, teaching younger doctors...
Dinner - a famous chef agrees to help a restaurant that is losing customers... not really romance though, if that's what you want. (I did see it between the lines)
Maybe also The King of Dramas - a drama producer so good that he doesn't care about hurting people and other people don't want to work with him anymore...
