Dongwan went out to city to get some fresh air. He couldn't believe what he just saw back there. He's lover was alive and a spirit. There were a lot of things to get worried about. Then, he sees a flyer.

"Some guy named 'M'. Sounds interesting." (Dongwan)

He buys a ticket and goes to the concert hall. He sees this 'M' guy and tries to approch him.

"Sorry. No one goes in." (Staff)

"That's okay. He can come in." (M)

"But..." (Staff)

"When I say it's okay, it's okay." (M)

"Yes." The staff says lifelessly. There was something going on.

Dongwan follows M to his dressing room.

"Uh... Thank you." (Dongwan)

"No problem. I do anything for my fans." (M)

"Actually, I just came to see the show. I was wondering about you." (Dongwan)

"Wondering about me?" (M)

"Yes. I've been wanting to know you. Where did you come from? How come I never heard of you until today?" (Dongwan)

"That's actually a common question I get. I debuted just a few months ago and I already have this many fans. And I have a secret." (M)

"What secret?" (Dongwan)

"I'm only telling you. I'm a spirit." (M)

"You mean..." (Dongwan)

"Yes. I'm Muse. But don't tell." (M)

"I won't. But can you tell me your real name?" (Dongwan)

"All right then. My real name is Minwoo." 

"I knew it. Minwoo, you're alive." (Dongwan)

"Yes, Dongwan. I'm alive." (Minwoo)

"But how?" (Dongwan)

"After I died, I heard a voice. It said to me that I can be alive again." (Minwoo)

"And you did." (Dongwan)

"Yes, but now I'm being hunted." (Minwoo)

"We're not hunting you. We just want to bring you and other spirits to peace." (Dongwan)

"Not from you. The spirit killers. They're after me." (Minwoo)

"But I thought they disassembled when the original spirit disappeared." (Dongwan)

"They did but they're back." (Minwoo) 

"Don't worry. I'll protect you." (Dongwan)

"Promise?" (Minwoo)

"Promise." (Dongwan)

After the concert, Dongwan was returning to Lost Child when suddenly he was attacked. He couldn't see what attacked him but he was sure it wasn't Minwoo. Just then, everything went black and he fell unconscious. When he woke up, he saw someone.

"Who... are you?" (Dongwan)

"I'm one of the two who the original tried to make spirits out of."

"What!" (Dongwan)

"Don't worry. I'm not a spirit. I only have spirit powers." 

"But then how are you still human?" (Dongwan)

"I survived from becoming a spirit." 

"Oh. Then what happened to me?" (Dongwan)

"You were about to turn into a spirit."

"What?! What do you mean?" (Dongwan)

"That's okay. I prevented it from happening. But you still have spirit powers." 

"Spirit powers? You mean..." (Dongwan)

"Yes. Like me, you are a spiritual human." 

"Spiritual human? Wait. What's your name?" (Dongwan)

"Just call me the spirit hunter. You'll need this." He gives him a crystal shard.

"What's this for?" (Dongwan)

"To seal a spirit's powers." (Spirit Hunter)

Dongwan went back to Lost Child. He couldn't believe what happened to him. 

"Dongwan. You okay?" (Eric)

"Yeah. That walk really helped." (Dongwan)

"Looks like you did more than a walk." (Junjin)

"About that... I encountered a spirit." (Dongwan)

"What?! Why didn't you call us?" (Eric)

"I fainted after getting attacked." He had to lie about that. He had to lie about so many things, like him meeting Minwoo who turned into a spirit that attacked them the other day, him almost turning into a spirit and saved by a person calling himself the spirit hunter.

"By the way, commander Joon wants to see us." (Eric)

They go to HQ and see the commander and his team. 

"Team S, we have a problem." (Joon)

"The spirit killers?" (Dongwan)

"How did you know?" (Joon)

"I saw them eariler today. They were hunting a spirit." (Dongwan)

"That's not good. We have to bring them to peace." (Joon)

"Yes, sir. We'll get on it." (Eric)

They go out and see the spirit killers. They were trying to attack Minwoo but wasn't successful.

"Stop! You're hurting him." (Dongwan)

"You again. Why does Lost Child even exist?" (Killer 1)

"Because we bring peace to all spirits!" (Eric)

"And we won't let you do that. Spirits need to be killed." The spirit killers attack.

"AH!" Dongwan gets hit more and more. Minwoo sees what they are doing to him. He couldn't stand it.

"No." (Minwoo)

"What?" (Soldier 2)

"NO!" Then, a dark light surrounds him.

"What's happening?" (Junjin)

"He's inversing. That's not good." (Taewoo)

That was not good at all. Minwoo turned into Meno, an inverse form of Muse. His angel, Maestro, was also turned into Mineur. He attacked the spirit killers and went towards Dongwan.

"Don't worry, Dongwan. I won't attack you." (Minwoo)

"You... won't?" (Dongwan)

"Yes. After I'm done with them, I will find the one who killed me." (Minwoo)

"Minwoo, wait!" (Dongwan) But then he was already gone.

Back at base, Eric and Junjin were wondering what happened there.

"What happened back there?" (Junjin)

"Yeah, and you knew the spirits name." (Eric)

"Actually, I never told you this. I went to his concert eariler today." (Dongwan)

"You did what?" (Eric)

"But he said he'd never attack me. He still has feelings for me." (Dongwan)

"But still. What also happened?" (Junjin)

"I... don't want to talk about it." (Dongwan)

"Hyung, wait." (Junjin)

"Let him be, Jin-ah. He needs his own space." (Eric)

Dongwan goes to the rooftop of Lost Child's base. He looks at the crystal shard given to him by the spirit hunter.

"What's this for?" (Dongwan)

"To seal a spirit's powers." (Spirit Hunter)

He remembers what he said. He needed to seal Minwoo's powers in order to protect him. But how can he do that? And how can he control his own powers if he's never used them before?
