He transmigrates into an alternate history and becomes a useless wastrel who died suddenly in a brothel.
He is the son of a prince, and his grandfather is a powerful commander who controls a vast army.
All he wants is to listen to music in the pleasure quarters, seek out women on pleasure boats, and spend his nights in drunken revelry... But...
The foreign barbarians want him dead.
The powerful clans want him dead.
Even the emperor is scheming to kill him.
Hanmo is baffled, but not panicked.
Under the guise of a wastrel, he advances one careful step at a time, cultivating the image of a good-for-nothing while secretly planning every move with the cunning of an old hand.
By the time everyone realizes what is happening, they discover he is no longer the man he used to be.
