I was upstairs in the room the Choi's made for me, reading over my notes from Biology Two. We had a test tomorrow. I would ask TOP if he wanted to study, but he would be at YG all evening.

I sighed and pushed my hair back. I was already in my pajamas, so I wouldn't be surprised if I fell asleep.

There was a knock on the door. "Come in." I said, looking at my notes.

Siwon poked his head in. He looked sweaty, and he took out the earbuds from his ears from his iPod, and pressed pause on the iPod that was in an arm holder around his bicep. He was shirtless, too. "Hey, how's it going?"

"Just studying." I sighed.

"What are you studying?"

"Biology two... I hate it."

" I took the class last year. I just got done going for a run, so let me go shower and then I'll help you, okay?" Siwon smiled.

I nodded. "Kay."

He left, and I looked back at my notes. I had been studying this for a week now and still didn't get it, so I don't know how TOP was going to even pass the test since he has t even opened his book. He's too busy training all the time.

After a bit, Siwon came back in, dressed in his usual sweats and now a tight black tank top. I couldn't help but notice how greats he looked, with his hair damp and his sweats hung low. His muscles made him look even better.

"Okay, so what chapter are you on?" Siwon asked, sitting next to me. I could smell his cologne, and it smelled great.

"Uh... Genetics and trihybrid crosses." I stuttered, showing him my book and notes. "I kinda get it but them again I don't."

Siwon took my book and set it in his lap. "Okay, yeah I remember this." he nodded as he read the book. "What are you stuck on?"

"Doing trihybrid crosses. I get that their like dihybrid but I get confused with all the numbers." I signed and leaned back, putting my hands behind me.

Siwon scooted closer to me to show me the book. My heart raced a little faster. We had never really been alone together before.

Siwon started explaining stuff to me, but who were we kidding? I couldn't focus on it no matter how hard I tried. He leaned in closer to show me something, and our hands touched. He didn't flinch his hand away, so neither did I. I also noticed my knee was touching his lightly, and that didn't seem to bother him, either,

"So do you get it?" Siwon asked after explaining, looking at me.

I nodded. "Uh... Yeah..." I lied.

Siwon smiled. "Good...." his smile faded slightly as he looked at me.

Why was he looking at me?

"Emma, I do really like you." Siwon said suddenly. "I mean, I like you more than a friend. I've always thought you were gorgeous. You're so kind with your siblings. You're funny. You have goals. I just... I really like you."

I froze. That was... Sudden. I'm not gonna lie, I liked him too. There was no doubt about that.

"Um... Wh-where are the kids and your mom?" I asked quietly.

"At the market. Emma... Can I just... Try something that I've been wanting to do for a while now?"

I looked at him and bit my lips nervously. "Uh, sure?"

I immediately knew what was about to happen.

Siwon tentatively leaned in, and when we were close enough, I closed my eyes.... And our lips touched.

I felt Siwon's hand over mine on the bed, and his other cupped my cheek.

My veins were on fire. Oh my God, I was kissing Siwon!

He parted from me, to my disappointment, and looked at me to try to tell my reaction.

I wanted more.

I squeezed his hand, and this was enough hint to him about what I wanted.

He kissed me again, more intense this time.  I circled my arms around his neck, and I felt him place one hand on my bare thigh.

Slowly, I brought him closer to me, and laid back, our lips not parting at all.

Siwon had his hands on either side of me, using his forearms to keep his weight off me, our bodies touching lightly. I ran my hands through his damp hair, my mind going at 1000 miles an hour.

Oh my God... What was happening?

Why didn't I want to to stop?

I felt one of Siwon's hands move to the hem of my shirt, slowly going under and touching my bare waist. I felt his tongue graze my lips just barely, so I parted my lips.

Oh my God, Siwon's tongue was in my mouth!

I was nervous, most definitely, but I stayed calm about it. I had made out with Ethan plenty of times back in Florida, so I knew the moves.

But how far were we about to go?

Siwon's hand traveled up my side, and I felt him remove his lips from mine, and travel down my jawline and to my neck.

I felt a certain pressure build up in my lower abdomen, and every touch from Siwon's hands made me want to beg for more.

Siwon's light kisses on my neck turned to and bites, and I gasped when I felt his mouth move towards behind my ear.

I couldn't help but moan when Siwon bit that spot, my back arching, causing my chest to press against his.

I put my hands at the hem of his tanktop when he kissed me again, and began to pull it up, but we both stopped what we were doing immediately.

Footsteps were coming up the stairs.

Siwon immediately rolled off of me and sat up, and I did the same, tugging my shirt down and fixing my hair.

There was a knock on the door, and Siwon quickly grabbed the Biology Two book and flipped it open to a random page. "Just play along." he muttered.

The door opened, and Siwon spoke. "Which is why the chemical equation for sugar is C-6 H-12 O-6, and not H-2 O."

"Ohhh, okay." I nodded. "Yeah, that makes so much sense."

Siwon looked up from the book. "Oh, hey, Appa. You're home early."

"Yeah, I need to work on that case." Mr. Choi sighed and ran his hand through his hair. He was wearing his police uniform. "What are you two up to?"

"Just helping Emma study." Siwon nodded, gesturing to the book in his lap.

I nodded in agreement. "I have a big test tomorrow, and Siwon took this class last year."

Mr. Choi nodded. "Where is everyone?"
"Umma and the little ones are at the market, Seunghyun is at YG, Minho is at soccer practice, and Mason is at Kyuhyun's house." Siwon answered.

Mr. Choi nodded. "I'm going to go work on this case."

He left, and I let out a shaky breath and pushed back my hair. "I... Uh..." I let out a nervous laugh.

Siwon chuckled. "You okay?"

I nodded. "I'm.... Just... I need some water." I quickly got up and grabbed my crutches.
