Danssisega Mangnaniga Neomu Gangham
Joo Hong-Mun, a low-ranking warrior who secretly learned the secrets of the Dan family, collapses helplessly before the attack of the Black Flame Sect and eventually dies lamenting his lowly status. But when he opens his eyes? He has become Dan Wol-Bin, the fourth son of the Dan family, notorious for being a loser. Not only has he returned to his pre-existing state, but he has also become a top-notch martial artist.
“From now on, I will change things with my own hands, and I will protect the Dan family!”
But this damned Dan family has more than one or two things to fix. A loser in his second life, he embraces the memories of his past and his martial arts skills, and his activities begin!
