In the darkness of the night, Red slummed the door behind him as he entered the place he was staying. No one is around so he is free to vent his anger into anything. He took off his long black coat with anger as he threw it on the floor. The phone in his hand was almost crashed by his strength but he would never shatter it as it's the only thing he could use to contact the detective, the officer and the only person he trusts.

For him, seeing Detective Lee living his life free and getting better is making his blood boil. Red wanted the Cameron to suffer, to be in pain. He wanted to see that person to be in a living hell. Hearing him acting like he doesn't know anything made Red even more ferocious and mad. If he haven't planned for everything in such a long period of time, he wouldn't wasted any day watching him from a far. He would immediately show up and kill him with his own hands.

But he had decided that wasn't enough. He won't just let him have a peaceful and quick death. All the killings and the clues he left are part of his plan. Ending those people's lives are part of his plan and to him, it was also to get them pay for there sins and helping them get away from living their miserable lives. Aside from that, he wanted him to remember everything, piece by piece and repeatedly like a broken music cord. All the the people who died, Red left them a clue.

"Just wait and see. Just a little more time and I'll make you suffer like hell. I'll make you remember every bit of it. I'll make you remember who Lee Jin Hong is. Just wait, detective!" Red said in an angry voice as he stared at the detective's younger photo.

He's been keeping that for a long time as he plans for his so-called revenge. Staring at his photo made him angry and motivated. Red clenched his fist while his eyes are flaming with anger.

"Hyeol, you went out again? Did you went to follow them again? I told you it's dangerous." A man's voice came from behind him.

Red walked towards the window, letting the wind play with his hair. "Jin Su, you are not supposed be here. You have your case to investigate, didn't you?" He spoke.

"Red, I already told you not to go anywhere. Being outside alone is dangerous for you. That kid, Michael, knows you're appearance." Ju Jin Su said in a scolding yet worried voice.

"There's nothing to be afraid of, I'll never reveal my real identity, Jin Su. I am being very careful, those idiot will never know it was me even if I was standing at their territories."

"They won't but what if it isn't just somebody who recognizes you? What if it was him? You know Lee Han Se might—"

"DON'T EVER CALL HIM THAT NAME!" Red drastically turned to him, his eyes full of rage. "Lee Han Se is my brother but that person isn't."

"I'm sorry. I'm sorry." Jin Su apologizes. "I'm just worried about you. We've spent a lot of time to create your perfect revenge plan and if you get caught, I don't know if I could do something to help you out." He said in a concerned voice.

Red smirk devilishly. "Ju Jin Su, you don't have to worry because I'll never get caught unless I intentionally bait myself to them." He stated as he walk towards the couch, sat down and crossed his legs.

"You can't stop me from worrying, especially when you're taking the dangerous way. Being near him is like baiting yourself, right?"

"I am danger, Jin Su."

"Hyeol..."

"Don't worry about me, I can handle myself. For now, just do what you're supposed to do." Red wave his hand.

"I understand. Anyway, stop overusing the sedatives I gave you to put your guards to sleep. I gave them to you so you could use them in case of emergency." Jin Su sighed.

"Don't worry, I'm a smart guy. Anyway, how's the thing I asked you to do? Have you taken care of it?" He asked while playing with a knife in his hands.

"Yes, I killed him and the handkerchief was given to detective Lee already. You followed them all day, how come you didn't know?" Jin Su furrowed his brows but Red just laughed while shaking his head.

"I'm just testing you. Of course, I already knew that you did your mission smartly. I even called him to say that I was the one who left him the gift, he sounded really nervous and confused. But to me, he sounded more like stupid." Red said that as if he was talking about a very good news. "Jin Su, I have one favor that I'd like you to do for me." He stated with an evil expression in his eyes.

"What is it, Hyeol?" Jin Su asked, Red turned to him with an evil grin.

"It might not favor you, so you can have a chance to refuse me."

"No, I'm going to do anything for you, Hyeol." Ju Jin Su insisted.

Red smirked. "But not the very first favor I asked you when we first met. I asked you to stop calling me Hyeol."

"That's the only thing I couldn't do for you, Hyeol. Your name's the only thing that reminded me of who you are."

"Fine, alright. So this is my favor for you..."

After being told of what he has to do, Ju Jin Su left the premises and prepared to do what he was told. He was hesitant with the idea but Red is very important to him that he could never say no. He considered Red more than a friend nor a brother. Red is his other half in a very significant matter. Helping him is the best thing he could do even if he has to kill everyone for him. Even if he has to sacrifice his life for him.

On the other hand, Detective Cameron Lee and Officer Chad were lying beside each other. Detective Lee's eyes were already closed but he wasn't asleep. He was thinking about Red and the thing he was claiming to be his. As for Devius, he was thinking that his partner was already sleeping. He kept staring at his handsome face, adoring every corner of it.

His perfectly curved eyebrows, long eyelashes and his pinkish lips. He's as handsome as those korean actors that Daena was crushing to.

"Cai, I can't believe that you're lying beside me now. I'll do whatever it takes to make you happy." He whispered and place a sweet peck on his forehead.

Cameron grabbed the officer closer to him. "Just stay beside me, that'll make me happy." Devius was slightly surprised when the detective opened his eyes with a smile after saying that.

"I thought you were already sleeping, Cai. Tch!" Devius pouted.

Cameron smiled a little wider, wrapping his arm around Officer Chad's shoulder, pulling him close to his chest. "My eyes are closed but that doesn't mean I'm asleep. I was just thinking about our case, the Killer Caller." He stated.

"You are supposed to be resting and you're still thinking about work? I really admire your passion." Devius admiringly praised his partner.

"What's there to admire? It's my job, I am supposed to do it correctly. He said humbly.

"Alright, you're so humble." He giggled.

"This is the hardest case I've ever handled, Chad. It's been almost two months and there's still a very little progress." Cameron sighed.

"Yeah. I could say the same. This case is really the hardest to solve in all the cases I've handled before. Do you think, well be able to catch the culprit?"

"I'll make sure to catch him even if I have to walk through the needle's hole. But what's bothering me is Red, the person who called me before." Officer Chad confusedly looked up at Cameron when he said that.

"What do you mean? The one who sent you the riddles?" He asked, furrowing his eyebrows.

Cameron felt hesitant at first but opening his heart and considering his feelings includes trusting Devius. He ruffled his partner's hair gently and stared at the ceiling.

"Actually, that day when you found me passed out on the ground, that's the same day Red introduced himself to me." Cameron confessed, Officer Chad sat up.

"What?"

"Yes, he partially introduced himself to me but I didn't see his face because of how dizzy I was."

"I'm confused, Cai. What do you mean he partially introduced himself to you?" Devius questioned, wrinkling his forehead.

Detective Lee sat up too and leaned on the bed behind him. "Well, he didn't fully introduced himself but he told me that he was the man behind the black coat."

"The man behind the black coat?"

"Yes, that's what he said. I saw him too." Cameron nodded.

Officer Chad was silent for a while. "You mean, the mysterious guy that the witnesses claimed to have seen before the murders happened." He asked in surprised.

"Mm. He might or might not be the same person but that black coat guy, I've seen him spying on us. Red called me and he admitted that he was the person following us." Cameron honestly confessed in along litany.

"Cai..."

"But I have this feeling that he might also be the one who killed the guy from the parking lot." Detective Lee sighed.

Officer Chad was feeling confused. He doesn't know how to respond after hearing all of that. If Red was behind everything, why would he give them a clue. But also, how did those guys found out that they were looking for them? And why would Red tell Cameron about his identity? All those questions filled his mind but no answer could be found.

"But wait, how did you know that he was behind that man's murder?" Devius furrowed his brows.

Cameron sat straightly and looked into his partner's eyes before saying, "Because he called me that same day and he said that the bloody handkerchief was his gift for me. That handkerchief... I remember that I used to have the same one and I also remembered writing my name in it."

"What?" Detective Lee's confession confused Devius more. "I don't understand, Cai. So, that handkerchief is yours?"

"No. No, it's not. It's not mine."

"Are you sure?"

"Yeah, the name embroidered in that bloody handkerchief is korean." Cameron said.

Devius turned to face him. "Well, aren't you korean too?"

"Yes, but my korean name is Lee Han Se and the name written on that bloody handkerchief was Lee Jin Hong." Cameron shook his head.

"But, why did you have such reaction with that handkerchief?" Officer Chad mumbled, confused.

Cameron took a deep breath. "I'll tell you some other time. Let's sleep now, I'm feeling tired." He ruffled Officer Chad's hair and lied down.

Even if Devius still wanted to ask him some questions, he knows that Cameron isn't that ready to tell him everything yet and he accepts that. He can wait until tye detective gets comfortable speaking about his past. Devius just lay beside Detective Lee, hugging him until they both fell asleep. But in the middle of the night, the pair was awoken by a loud knock on their apartment door.
