Once upon a time, a boy was referred to as a “War Hero.”

In another world called Aletia, the boy who had saved the Lost Kingdom, conquered their neighbouring countries, and led to the rise of a grand empire decided to throw everything away, returning to the modern era at the cost of his memories.

As three years passed, the boy who was happily enjoying his daily life was once again called back to the other world.

However, what awaited him was the Aletia of 1000 years in the future.

As his past glories became a “myth,” the legend of the youth referred to as the, “Twin Black Hero King,” begins.

“Your Majesty, someone cursed the Imperial Concubine to be a demon star.”

“Cut his tongue and feed it to dogs.” A certain King said in a light and gentle manner.

“Your Majesty, someone’s hand accidentally bumped into the Imperial Concubine.”

“Chop his hand and feed it to wolves.” In an indifferent manner, a certain King said possessively.

“Your Majesty, someone said that the Imperial Concubine ran away.”

“Ran away?” A certain King’s sharp eyes narrowed, then said with a sneer: “It’s best if she doesn’t get caught by this King, otherwise this King will let her become aware of what ‘wanting to stop but can’t’ means**.

A modern era crossed over to become a wolf-girl. She originally believed that she could dance around with wolves, and in the end she truly did, but this ‘wolf’ was one of those wolves. He was a perverted wolf!!
