This is just a martial arts version of the story of Romeo and Juliet.
But this time they corrected their mistakes when they knew they were wrong. They didn't make the same mistake again and again. They chose to forget each other in the world.
When we met again, she was still the unruly girl who refused to admit defeat, but he was no longer the indifferent martial arts young hero before, and was very soft-hearted.
Can they really avoid making the same mistakes again and again?
