I know I have one, Empress Ki and I wish everyone watched it, but I know everyone has a favorite so I want to watch them :)

Just one favorite from each!

Country, language, doesn't matter, I want to try it all.

Stranger (sometimes called Forest of Secrets)

 Popcxqueen:

Stranger (sometimes called Forest of Secrets)

It was already on my watchlist :) I will watch it soon, the Bae Doona is a favorite of mine.

I'd love to hear what you thought when you watch it. :-)

I'd say Mr. Sunshine... but it looks like you already watched it so... Mother <3 (The Korean remake, I haven't seen the original Japanese one >.<)

Nirvana in Fire (China Historical)

There nothing called absolute favorite for me, so I would say  The spies who loved me.

A C-Drama Titled You are My Hero.

One of my 10/10 favourites that you have not seen: Hello Harinezumi (jdrama)

Suika

I was considering recommending Nirvana in Fire, but I see that 2 people already did, so I'm recommending Suika instead (I'd give them both a 10/10).

Prison Playbook (2017) is my all-time favourite drama but I see that it is already in your PTW list so I'll recommend In Family We Trust (2018), a thai gem that I discovered this year!

I've been considering Nirvana in fire, but I'm a sucker for romance and there doesn't seem to be any.
