I've only rated 6 dramas a full 10 rating:
1. Another Miss Oh - BREATHTAKINGLY AMAZING. It definitely brings out the feels; it has likable characters all-around and they react to things in relatable/realistic ways.
2. Signal - The best non-romance drama out there. It's woven together PERFECTLY. So, so good.
3. That Winter, The Wind Blows - It has one of my MOST FAVORITE actors ever: Jo In Sung. This drama brings out the feels like no other. It's my favorite melodrama.
4. The Princess' Man - If you are new to sageuks, this is a drama not to miss out on. Epic romance, epic storyline, epic everything. <3
5. Kill Me, Heal Me - Ji Sung absolutely SLAYS in this drama. So, so wonderful.
6. It's Okay, That's Love - Another Jo In Sung drama; this brought out feels, laughs, and just general amazingness. One of the very greats. <33
