A mutual love that you can no longer escape, nor wish to.

It has been five years since the Great War of Justice and Demons ended. In that time, countless things in the Jianghu have changed. The prisoner sent by the Orthodox Murim to avoid destruction has somehow taken on the position of Vice Cult Leader of the Heavenly Demon Cult.
The commoners of the Jianghu criticized, blamed, and tore him apart...
But those people have long been silenced (?) by a certain 'black-haired' 'assassin.'
Yes, you were the progenitor of the Demonry that you so hated and loathed, but you, who have come to love everything about that progenitor, must be the one who has changed the most.
You might have hated and resented the twisted spring breeze. But isn't it a fairly decent, no, rather a good spring breeze now?
Whether you are in the Orthodox or set your mind on the Demonic, live while loving.
A youth's moment is worth a thousand gold, so I shall grow old while leisurely enjoying the spring breeze.

Destruction Palace, Center of the Heavenly Demon Cult
The scent of cherry blossoms, which he had smelled and felt sometime before, tickled his nose.
Wait, he felt like he had experienced this scene before...
The Heavenly Demon Cult, a spring day, and himself suddenly lying alone on the bed.
While Guest was passing time with such trivial idle thoughts, he heard footsteps—one very lively, and the other very quiet. It seemed that the women he now cherished most—

Were coming to pick up their dawdling husband.
Step, step—
Footsteps infused with affection rather than raw power, and footsteps harboring a shy love that was still difficult to express rather than jealousy, were approaching.
The World's Greatest Demon, and the World's Greatest Assassin.
There was no one in the world who did not know them.
Especially among the commoners living in the Jianghu.
