We walked back home hand-in-hand. I had told him I accepted his confession. He was more than happy to call me his girlfriend now. But we still didn't know how to tell our parents.

“Maybe we should have a nice dinner and tell them.” he said.

“But what do you think they'll say? Do you think they'll be happy? Sad? Freaked out? I mean...we are brother and sister.”

“By papers.” he corrected.

“Right...but I don't think we should tell them yet. We don't even know if this will work out or not.”

“Why won't it?”

I shrugged. “I mean everyone knows we're brother and sister. What will they think if they found out we're together? It can only cause trouble.”

“I guess you're right. Once we figure all of this out, we can tell Mom and Dad.”

“So what did you guy do when we were gone?” Mom asked at dinner. They had came back a couple of hours ago.

“Well we went the amusement park.” Siwan explained.

“Really? Sounds fun.”

“It really was.” Siwan smiled at me.

“Not really. It was chilly and stuff.” I said.

Siwan raised an eyebrow.

My dad nodded. “I hope you wore a jacket.”

“Oh I just noticed! You guys have couple shirts on! How cute~” my mom squealed.

My eyes widened. “U-uh, it's me and Sun Mi's matching sweatshirts. I let Siwan borrow it.”

Siwan frowned.

“He can fit it?”

“Yeah, a little small but it worked.”

Silence.

“I'm full.” I said and ran upstairs.

I sat on my bed and played a game on my phone.

I heard a knock at the door.

“Come in!” I called.

Siwan walked in and closed the door behind him.

“Hi Oppa.” I said and set my phone aside.

“I don't like this whole keeping it a secret from them ordeal.” he said, sitting down next to me.

“Why?”

“I don't like seeing you so paranoid. It's not healthy.” he laced our fingers together.

“I'm sorry. I'm just scared they'll find out. They're parents after all. They have eyes on the back of their heads.”

He laughed. He lifted my chin up and kissed me.

“You're so cute.”

I giggled. I could definitely get used to this.

“But hey, don't worry about it. They won't know anything.”

I nodded and he kissed my forehead.

“Hey Eun Byullie, I bought you a--” my mom opened the door.

Siwan and I immediately scooted away from each other.

Our mom gave us a look. “Did I interrupt something?”

“N-no.” I cursed myself for stuttering.

She raised an eyebrow and set a bag on my desk.

“Thanks Mom.” I said.

“Mmhmm...” she gave us a suspicious look before leaving.

I sighed and laid my head down on the pillow. “That was too close.”

Siwan got up and locked the door.

“Now where were we?” he smirked and hovered over me.

He kissed me all around my face before kissing my lips.

“Seriously Siwan! She could've caught us.”

He sighed and laid down next to me. “Everything's going to be fine. Plus, what's the worse they could do if they find out? Un-adopt me?”

“Is that possible?”

He shrugged. “But that wouldn't be too bad...then we wouldn't be 'related' anymore.”

“But I want to keep living with you.” I put my head on his chest and listened to his steady heartbeat as he wrapped an arm around me.

As we walked to school the next day, he grabbed my hand. I took my hand away.

“I can't hold your hand?!” he asked in disbelief.

“Someone could spot us. Plus, do you really need to? I mean you already have my heart.” I smiled at him.

I saw his face soften. “Why do you do this to me?”

I smirked and skipped through the school gates.

“Hey wait!”

When he finally caught up to me, we were inside.

He grabbed my wrist and turned me around.

He started to lean in.

“I want my goodbye kiss.”

“What?!” I pushed him away. “We're in school! Someone might see us!”

He looked around. “Come on, no one's looking. Plus, I want to show off my girlfriend.”

“Everyone knows we're brother and sister. They're gonna think we do .”

“We can just say I was adopted.”

“Say it to 600 other students? Too much work.”

“Fine. Then come here.”

Before I could say anything, he pulled me into an empty classroom. He pushed me up onto the door and kissed me.

I gotta say, all the snooping around made the kiss much more scandalous then it already was.

“Sit with me at lunch?” he asked, when he pulled away.

I nodded.

Siwan left first and I left about 30 seconds later. When I reached my classroom I saw Myungsoo helping a girl pick up her books.

I bit my lip. What about Myungsoo?!?!

He saw me and ran up to me.

“Hey sorry I couldn't walk you today. I had to come in early for some tutoring since I can't stay after today.” he apologized.

“It's okay. Siwan oppa walked me.”

“So do you want to eat with us again today?” he asked.

“I'm eating with Siwan oppa today. I'm sorry.” I was starting to feel bad. I had lead him on all this time when my feelings for Siwan were always stronger. Why was I such a horrible person?

He frowned. “You guys live together. Do you have to eat with him today? I miss you.”

“I'll sit with you at the second half of lunch.”

“Better than nothing. See you.” he waved.

I waved back.

As soon as I got in the classroom, I started to debate on if I should tell Myungsoo or not. He'd keep it a secret right? He wouldn't get so mad that he'd tell the world right?

Man...this paranoia is getting to me.

I sighed. This is gonna be hard.
