this is kind of tricky cause I don't speak korean so watching a drama in the background without actually understanding anything will be a bit meaningless, so maybe something I'd already watched like:
9. Kind the Land - this is so anti climatic so if I'll miss some (most) parts it won't be that much of a loss.
10. Romance is a Bonus Book - it's a really cute Kdrama and I enjoyed it alot, but could also watch it as a background when I do other things and come check on it from time to time~
If these are ok then next person can pick :)
