This was largely a random Netflix find, possibly loosely inspired by a recent conversation at work about how ghosts occupy a different place in East Asian culture to Western culture. Oh My Ghost (2015 tvN) also heavily features chefs and cooking, which I have recently realised I am a big fan of in my TV choices. And the trailer for it looked light and silly, which appealed to me.
Oh My Ghost is a combination of sweet romance, crime drama and supernatural comedy, and it handles all those elements really well. It discusses sex and passion reasonably openly, for a K-drama. And the leads are very beautiful. Which means this comes pretty high in my ranking of K-dramas, despite my low expectations.
