Has anybody seen the Korean manhwa Rure by Seomun Da-Mi? It was first released in 2003 and is still ongoing. This series has shaped my love for fantasy ever since I first read it in 2010. The epic plot, the worldbuilding, the characters, the relationships, the power structure, this series has it all. It was even translated into English in 2008 by Tokyo Pop (only three volumes tho..)
Anyway, if anyone is looking for loving you is defying destiny, chosen lovers over soulmates, our destiny is for our taking, you make me want to love myself and every delicious trope including a shove-it-I'm-doing-it-myself female lead and shoot-destiny-loving-you-is-my-salvation male lead, please, PLEASE!!! read Rure.
