Korea is one of the safest countries, with no firearms even being carried by anyone except police officers. However, recently, illegal weapons have been circulating, giving them to certain individuals. Korea is currently experiencing an illegal arms shipment. Moon Baek, the leader of this criminal enterprise, is still hiding his true identity. He even lives like a normal person and helps the police.

"Crazy, people are really dangerous these days. Come to think of it... why are they doing all this?"

Moon Baek said enthusiastically, as he acted like a funny and friendly man

"If this continues, Korea will be filled with chaos. We really have to solve this..."

Moon Baek said to Lee Doo, his fellow police officer who helped him. Moon Baek looked relaxed, smiling as usual
