Uprising (2024)

Both are historical stories about two friends with different statuses who end up enemies due to choosing the opposite side of some conflict.

Even Though Uprising hasn't started airing yet, based on the trailer, I can say there are some similarities with the drama My Country: The New Age.
In both, two men from different status, one is noble while the other isn't, are friends but, in the end, they become ennemies and have to meet on the battlefield.

Both utilized the history of The Revolutionaries during the Japanese invasion. TBRTV were fighting the Japanese invaders, whereas Uprising included the fight against lower class suppression.
