Penance is a prison of eternal damnation for those who go against the will of the gods.Growing up in the slums of District Nine, Nacht was like every other individual his age, struggling to survive with what little he had and blaming the capital for it.

However, that all changed when his mother was offered up as a sacrifice to the capital to help bolster the number of Enlightened in their arsenal.The Enlightened were elite warriors who wielded supernatural powers and served their respected clan at the cost of sacrificing an individual for the opportunity to enter Penance and be bestowed or awakening a rune, the source of their profound power.Having been exposed to the worst of humanity due to the horrific execution of his mother, Nacht developed a relentless ambition to change the world—even if it was in his own unconventional way.After performing a disgraceful ritual, Nacht is sent into Penance, where he becomes one of the Enlightened and is bestowed a mysterious power along with an insidious punishment.

When Su Yaya awakened, she found herself in a novel world as the CEO’s Substitute Wife–-a mere cannon fodder. Knowing that divorce and a tragic ending was awaiting her once her look-alike, the President’s first love returns, Su Yaya only trusted one thing: Money.

She curried favor with her husband each day, saved up resources, and served him as a faithful wife. It was better to leave a good impression on him before separation so she could avoid her death flags.

The overbearing President was very satisfied with her and personally gave her his platinum card: “Take it and buy anything you’d like!” Su Yaya happily accepted. Of course she would take advantage of his pampering before the female protagonist appears!

As the CEO unexpectedly falls deeper despite this transactional relationship, he never imagined that his wife would one day disappear from his side.
