[Suho's POV]

After I saw those picture, I felt my heart in pained. I don't even know why. I thought Cheonsa was like a Cheonsa to me. An angel.

But I was wrong.

She's the type of girl like to play around with boys. I never thought she would do this to me. To my own half-brother. I clenched my fist to hold my anger. 

"What's wrong oppa?" Sunmi came to me and hold my waist. I'm at her place. "I'm just thinking of something." I held her head and put it on my chest. She stroke my back. "Relax oppa. Don't think too much." I smiled and kissed her forehead. At least Cheonsa should be like Sunmi. "I'll need to go now. It's almost 11 pm." She pouted. "Can't you just stay here for a while? Just sleep in my place." 

I think that's a great idea. I don't want to deal with that girl face. I nodded and we both sleep together.

~ FAST FORWARD ~

I came home around 2 pm. I can't even sleep. I don't know why. I shouldn't think too much. I've been doing this for 2 weeks already. But today, I feel so different. A small light came from my room.  That's strange. Did I forget to switch off the light? I came in to my room and I was surprised. A sleepy Cheonsa with her face on the table sleeps peacefully. She's sleeping on her books. It's a bit messy though. What's she doing here? I sighed hardly and put my things on the bed. I lifted her up in bridal style and move her to the bed. I saw her moving her body and slowly her eyes opened. "S-Suho?"

Damn it, I don't want to see her face. I gulped at my own saliva. She blinked few times. "It is you." she finally woke up.

"What are you doing in my room?"

She sat down and looked at the table. She rubbed her nape. "Well, I feel like I want to study here for my exam but some of them I can't solve the problem. I was waiting for you."

Waiting for me? Tsk~ you shouldn't do that. I smirked at her. 

"Why don't you ask your boyfriend to do solve it for you?" She looked at me. "What do you mean?"

"Don't pretend to be innocent. I'm talking about you and Kai." She widened her eyes. "I told you I can explain."

"I don't need to hear it. It's clear enough. So now, pack your things and get out." She slowly nodded and stood up from the bed. She clear the things and went in her room. I sighed hardly and held my chest.

Why do I feel so heavy?

"You know, Kai oppa and I are not together. We're just hang out together plus he said honest things to me." Before she went out from the room. She sounds like crying. Her voice us cracking.

I looked at her. She's crying?

"Kai said she loves me but I didn't accept him. I told him I'm married to you. He's a brother to me." I kept in silent and listen to what she's said. 

"I never thought you would do this to me too. You always came home late these lately."

"Don't mind about people business."

"I'm your wife Suho."

"I don't know if I could think you as like that." Her tears keep on rolling. "So, you came home late because of Sunmi?"

"Yes."

"I hate you Kim Junmyeon." she mumbled but I could hear it. 

"You can hate me. I won't change my mind." She ran out from my room and slammed the door.

Then, Kai came to my room.

"What?"

"We need to talk hyung."

[Cheonsa's POV]

I came to my room and cried. I can't believe Suho did this to me now. I hate him.

I really hate him!!

It's hurt a lot. How could he said that? He sleep with the other girl plus he came home late. I sleep late because I was waiting for him to come home. My examination is near and I feel like I won't be pass. I can't even talked to Kai now. Maybe I'll just skip my school and don't attend the examination.

- The Next Day -

I woke up and my head hurt.  Gosh!! I sleep while I'm crying last night. I can't even stand up. I feel so super cold. Then, my door opened. I quickly closed my eyes. Pretend to sleep.

"Cheonsa.."

Suho's voice. Don't opened your eyes Cheonsa. I felt my bed bounce a little less. Did he sit down? I felt my forehead was been touch. "Cheonsa!! Yah!! You're burning!!" I slowly opened my eyes. His face was in panicked. "OMG!! What did you do!?" he was very concerned on me. He quickly asked the maid to damp water on a towel. He took a bowel of water and damp the towel. He squeezed it and put it on my forehead. "I'll take your breakfast." Why is he being so nice to me?

That's weird.
