Okay I just reread season 3 and noticed the heavy parallels between this and A cruel god reigns (my favorite manga), they're similar up to the end even! Leaving it vague and like a promise.
This might be one of the biggest reasons why I love it so much, the complexity of the story and the characters themselves are so wonderful.
Also the story isn't similar at all, just the self doubt and self destructing nature shown by YO in season 3 and the desperation of Kwon. They reminded me of Jeremy and Ian.
Although their story wasn't a typical happy end.
