Recommendations: very rewatchable jdramas

With some dramas you watch them once, and that's it. Doesn't mean they're bad, it's just the sort of story you don't want to see more than once, like with mystery dramas, once you figure it out once, you probably won't want to see it again that much.

But there are dramas whose message, episode pace, acting, etc., just REALLY makes you want to rewatch! These are jdramas I consider most rewatchable, by *ALPHABETICAL* order.
