1. Stairway to Heaven (2003)

In many ways,Stairway to Heavenis the quintessential K-drama of the 2000s, brimming with nearly every classic K-drama trope: amnesia, swapped identities, evil stepfamily, etc.

But it’s one of the most popular and iconic Korean TV shows of all time for its writing and execution that leaves no dry eye in the room.

Many viewers thought the series would end happily ever after when Han Tae-hwa (played by Shin Hyun-jun) made her noble-but-tragic sacrifice to Han Jung-suh (played by Choi Ji-woo). What’s more devastating is how the series leans heavily into Jung-suh’s terminal illness.

In the end,Stairway to Heavenexplores the question of which character had the greatest love to give—a great story twist right up to the end.
