Yun Hee's POV

 "Nae yeoja, why are you so quiet?" Key asked.

 "N-nothing." I replied.

 "C'mon tell me, I know something is bothering you." Key said.

 "N-no, it's nothing really." I replied.

 "C'mon," then he pulled me, "What the hell is that!" he said.

 I look at him. His eyes were wide open then it soon turned to a ferocious gaze.

 "Who the hell gave you that mark!" his voice thundered.

 "M-mark?" I asked.

 He stood up and grab a mirror and instantly show me where the mark is.

 I was shocked to see a red mark on my neck.

 "I-It's not what you think Key." I said.

 "You cannot fool me Yun Hee." he said.

 Then someone knocked at the door.

 "Yun Hee, Key are you okay over there?" it was Jonghyun.

 Key look at me, "It's his mark?" he asked.

 "N-no." I whispered.

 He stood up and was about to walk towards the door, but then I grab his arms.

 "K-key, please." I said.

 "I can't let this pass Yun Hee." he said as he shove my hands away from his arms.

 He immediately opened the door and found Jonghyun standing in front of it.

 "You!" he quickly gave him a punch right to his face.

 "Keeey!" I screamed.

 "Ugh!" Jonghyun groaned.

 "You bastard!" Key shouted as he at on top of Jonghyun and keep on giving him punches to his face.

 "Yah! What the hell is happening here!" Minho rushed to them.

 "Jonghyun!" Sekyung gasped.

 "Key! Stop that!" Yuri screamed.

 Minho was holding Key's arms, "Chill out Key." he said.

 I tried to stand up and walk but I fell.

 "P-please stop it." I whispered.

 "Ughh." Jonghyun was groaning in pain.

 Sekyung supported Jonghyun to sat up. Jonghyun is wiping his bleeding lips. Yuri was also at his side, while Minho is holding Key.

 "You ! How dare you mark my girl!" Key said furiously.

 Sekyung looked at Jonghyun, "What does he mean?" she asked.

 Jonghyun did not reply.

 Sekyung looked at me, "Yun Hee, what does he mean?" she asked.

 I look down and bit my lower lip.

 "You, Kim Jonghyun, don't you ever show your face to me or even to Yun Hee!" Key shouted. He pushed Minho away and walk to where I am. "We're going home!" he said, "We're not done yet." he hissed.

 He grabbed my arms and pulled me up. He glared at me and pulled my hands to walk where the door is.

 "Key, it hurts." I said.

 He coldly looked at me, "Bear with it, you had fun with another guy. You deserve that." he said and he continue walking.

 Jonghyun's POV

 When they left.

 "What does Key mean by that?" Sekyung asked.

 I stood up and pulled my arms away from her, "It's nothing." I said.

 "Hyung, if it's nothing then why does he have to be like that towards you?" Minho asked.

 "Leave me alone!" I yelled, "Don't ask me any question!"

 "Minho. let's just leave him for now." Yuri said, "Sekyung."

 "I'm going to leave you, but I expect that you'll give me an explanation later." Sekyung said.

 They left. I'm all alone, couldn't think straight.

 'What happened?' I asked myself.
