Mangnani Geomsaga Dallajyeotda

After working hard for revenge all his life, he became a lawyer with a 97% success rate. Now all that's left is to take revenge on that bastard, 'Smile', who killed his mother, but he ended up dying at the hands of that bastard...

"Prosecutor Jang Hyun-Soo!"
What? He's possessed by that bastard Jang Hyun-Soo? Is it a twist of fate? No, is God giving him one more chance?
"Smile, I'll definitely get revenge on you!"
