I liked Playful Kiss. Mostly because KHJ is fucking hot
I mean I know he's an asshole but he's still hot smh.
There's also Jackie Chan's city hunter lolFrom Korean adaptions City Hunter and Antique Bakery were pretty good though with those two I haven't seen the animes they were based on. Die-hard fans of those animes might not like them cause I think Antique Bakery is supposed to be yaoi when the movie did have some gay characters the main character wasn't into guys. And City Hunter's kdrama ver was pretty focused on romance and I kinda doubt original anime was.
