He helps his student run away from the villain organization while working as a bait to oure the enemy.
This manhwa is really lit. At start it feels like it is just a pretender type manhwa where the main character pretends to be a villain but he is a good guy but after some chapters shit really hits the fan and we start seeing a lot of action. This manhwa has a lot of good comedic moments and it can get a little bit dark sometimes. The art is quite good and there are a lot of satisfying and brutal fight scenes in it. Characters are also written very well and the world building feels really smooth.
The story follows a third-rate villain who tries to survive in the world using petty tricks and schemes, somehow making people misunderstand him to be a kind, strong, person. Eventually it leads to him to living with a hero and demon who also believe him to this kind, strong person. The characters seem to be mostly unaware of each other's identities, personalities, and powers, leading this story to be comical and harwarmingly family-like.
It's a fun read as long as you don't take it too seriously
