In Bloodhounds, Mr. Moon is the one who introduces Gun-woo and Woo-jin to Mr. Choi and joins them during the battle at Four Garden Mall. Park Hoon plays Mr. Moon.
Mr. Moon Gwang-mu is a former Marine from the 734th class. He used to work at Mr. Choi’s firm. When Mr. Choi feels that he needs to hire bodyguards for Hyeon-ju, he tasks Mr. Moon to search for potential candidates.
Mr. Moon meets a lot of applicants, but they all fall short. That’s when Woo-jin contacts him. Mr. Moon knows Woo-jin very well and sees him as the perfect candidate for this job.
Mr. Moon gets excited upon meeting Gun-woo as well. Both Gun-woo and Woo-jin have what it takes for this job. However, Woo-jin and Gun-woo were looking for a loan. Mr. Moon promises them that Mr. Choi will help them with that.
Throughout Bloodhounds, Mr. Moon serves as comic relief. He is also a great fighter and soldier and is proud of being a Marine, just like Woo-jin.
Mr. Moon faces Smile Capital
Gun-woo and Woo-jin train harder to defeat Myeong-gil after losing Mr. Choi, Lee Du-yeong, and Hwang Yang-jung to him. They plan to get back into the war, but first, they opted to look for more allies who can help them.
They see an ally in their senior Marine, Mr. Moon. When they visit his office, they find it wrecked. Mr. Moon shows up with injuries and bandages and reveals what happened.
It turns out that Myeong-gil’s associates had visited him and offered him a deal. They managed to con Mr. Moon too and gave him a beating as well.
Mr. Moon is left in utter shock after learning that this is Myeong-gil’s doing and that Myeong-gil has killed Mr. Choi and his lieutenants.
Mr. Moon joins the war
Myeong-gil later finds out that Gun-woo and Woo-jin are onto him. To tackle them, he kidnaps Mr. Oh. Myeong-gil’s associate, In-beom, invites Gun-woo and Woo-jin to Four Garden Mall if they want Mr. Oh back.
Gun-woo and Woo-jin needed friends, and they found one in Mr. Moon, who feels he is indebted to Mr. Choi. Mr. Moon shows up at the mall, covered in face paint.
Mr. Moon proves to be a great addition. Mr. Moon’s torture methods help Gun-woo and Woo-jin make one of Myeong-gil’s goons open up. Mr. Moon only fails with In-beom, who would rather kill himself than give any information to them.
