"What should I do now?" 
"How can I get in there?"
"Arghhh! Think! Byunghee! Think!" Byunghee asked himself and pulled his hair. Since he begun to spied on his target, Yang Seungho. Until now It's almost 1 week. That man wasn't came out from his house. He can't waited much longer. He wanted to come back home and showed his brother that he can do the mission with himself.

"You should get in his house and kill him."
"Kill? I think I can't." 
"Just kill. You can do it."
"No! I never kill someone before. I can't."
"If you don't kill him. You can't comeback home. Do you understand? Byunghee."
"I'll get in there and kill him." Byunghee said with himself again and again until he made the decision.
"Ah-ha. That way doesn't have the guard. You're so lucky, Byunghee." Byunghee said with himself as he used his binocular to found the way in.
"Let's go, Byunghee." Byunghee said with himself again before he tried to climbed up to the wall. While someone get out of his hiding spot and looked at him with his worried eye.
"I hope he'll understand whatever you wrote in that letter, Hyung." Sanghyun said softly as he saw Byunghee climbed up to the wall and get in the house.

……………….…………………………………

"How can I find him from the large area like this." Byunghee whispered to himself after he reached the ground and hide in the bush near him.
"Who's that?" Byunghee asked himself when he saw someone walked out of the room and stood at the balcony on the second floor of the house.
"Ah! That's him. Yang Seungho." Byunghee said softly with himself when he knows who's that man. Then he picked his gun from his bag and point it to his target.
"Do it, Byunghee. This is your only chance. Do it now." Byunghee told himself. But before Byunghee shot. His target looked at his direction before he walked out of the balcony and get in the room.
"………………………" Byunghee put his gun into his bag and looked at his trembling hand. He remembered that man's eye. He afraid of it.
"But you should do it." Byunghee told to himself and tried to calm down. He waited there until the lights in that room was turned off.
"It's time for you, Byunghee." Byunghee said before he walked out of the bush and tried to climbed up to the balcony on the second floor. When he arrived at the balcony he tried to pick lock the door until it unlock. Then he came in the room and saw someone slept on the bed. He walked to beside the bed and pick his knife from his belt but before he stabbed his target who slept under the blanket. Someone pushed him on to the bed and took his knife from his hand before he crawled up on top of him. When he tried to fight with that man his hands were tied with the rope. And when he tried to kicked that man, he noticed his right leg was tied with the chain. 
"Who are you? What are you doing?" Byunghee asked that man with his trembling voice. He afraid of the man who on top of him.
"I'm your target. Didn't you remembered me? You make me waiting so long, Byunghee." The man above of him said as he picked the gun from Byunghee's bag and placed it into the drawer. Then he pulled the bag from the owner and threw it on the floor.
"You! Yang..Yang Seungho!" Byunghee called the other's name with his shock expression.
"Yes. Yes. That's my name. And you asked me what I want to do, right? I want to do something  with you and I think you'll like it." Seungho said after that he kissed the younger on his lip then his neck as he tried to took off the other shirt.
"No. Let.....me.....go..." Byunghee tried fight against the older but he can't do anything.
"Be a good boy, Byunghee." Seungho whispered beside the other's ear before he continue to kissed Byunghee's and sliced his hand into Byunghee's pant.
"No. No. Please....let...me...let...go." Byunghee begged the older with his crying voice but it doesn't made the other changed his mind.
