Dramas for re-watching?!

I don't re-watch dramas because I don't think I have time for it. I prefer to spend the little time I have for watching on dramas that I've never watched before. I do, however, occasionally consider rewatching something because I miss this or that about certain dramas. Right now (November 2020) I'm rewatching Beethoven Virus. This made me thing that now that I have started rewatching, maybe I will also rewatch other dramas in the future. So I'm making this list... because lists are fun! ;)
