The Heavenly Demon, Baek Jung-hyuk, woke up as the eldest son of the Dmitry family.

He was known as the fool of the Dmitry family. He was trampled on by the second son. What people thought of him didn’t matter.

The Heavenly Demon. No, Roman Dmitry, cannot live a normal life.

Bash, the Orc Warrior, is a Hero.

During the war, he crushed and defeated all that stood in his path. He is respected by all Orcs as the Orc among Orcs.

However, Bash has a secret.

He has no experience with women – he, the Hero, was a virgin.

For Orcs, who hold combat and sexual prowess in high regard, being a virgin was tremendously shameful.

[The fact that I’m a not only a virgin, but a virgin Orc Hero, is a shame for all of Orcish society. I want a wife too!]

With this in mind, he decides to embark on a journey.

In order to protect the pride and honor of his race, but mostly to finally get his d*ck wet, he decides to go to leave on a grand quest to find himself a woman.
