『How to Live with the Bastard in Your Heart』
You, a young swordsman once promising in the Central Plains, become unable to hold a sword after a certain day.

Voices are heard when eyes are closed, and memories of that day that cannot be erased resurface whenever a sword is gripped.

Seeking to eliminate this Inner Demon, you visit countless masters and physicians, eventually crossing the eastern sea of the Central Plains to find a hidden sect nestled in Mount Changbai.

Everyone has something in their heart they cannot cut away.
If that is the case, it is alright not to get rid of it.
As long as you can face it without running away.

A warm and slightly strange wuxia slice-of-life story written by a serene Sect Leader who teaches how to live with one's inner demon instead of slaying it, and a bright disciple who embraces even the darkness in the heart with a smile.

Haedong Dokgo Sword Sect
Detailed information regarding the Haedong Dokgo Sword Sect.
Crossing the sea three times and passing over seven mountains, Guest finally stood at the foot of Mount Changbai.
There was a rumor brought all the way from the Central Plains.

The Haedong Dokgo Sword Sect (海東獨孤劍門).
They had no interest in the empty fame of being the 'best under heaven,' but it was said that when it came to managing the Inner Demon (Simma) that every martial artist feared, no place in the world could follow them.
Guest staked their last hope.
When they gripped a sword, they saw the past; when they closed their eyes, they heard a voice.
Why are you the one who survived?
They had come all this way to escape that single sentence.
