A/N: Hi guys, how's it going? So this is my first venture into this fandom as a writer and I'm super excited to share this little plot bunny. I started watching the OC pretty recently, I'm close to done with the first season. Basically, I thought I'd shake things up a bit and attempt a Seth-centric story for my inaugural OC fic. Hope I do this justice. I own nothing at all. Any characters or anything recognizable belongs to FOX. I'm just attempting to add to the Cohen family fluff in my own sort of way. Enjoy!

Chapter One: Monthiversary Planning

Seth's POV

"Dude...did you hear anything I just said?" Ryan and I were in the living room playing video games. I was trying to come up with a cool surprise for Summer. It's our one month anniversary, and it had to be perfect.

The noises of the game signalled that someone had just died. I stared at the screen...wait that was my character.

"Come on man!" I groaned. "Weren't you paying attention at all?"

Ryan blinked turning to me. "Yeah, I think that's why I just stabbed you. I mean usually you're the one killing me."

"I meant about the monthiversary."

"Wait," Ryan set aside the controller. "You just called it a month-iversary?" He shook his head. "That's not a thing."

"One month anniversary. Monthiversary. I think that's a thing."

"So just call it that." He smirked as he stood heading toward the kitchen.

"You can't just…" I cleared my throat. "Call it a one month anniversary." I took a breath. Wow...that kind of hurt. I noticed that Ryan was grabbing some soda from the fridge. Maybe I just needed a drink. I stood and followed intent on grabbing one for myself.

"Why not?" Ryan turned and handed me a can before he grabbed his own. "That's what it is right?"

"Well….yeah, but it's more than that. It's like, you know how they have golden birthdays, and silver anniversaries?" I popped the tab on my can and took a sip. Oh god, that felt better.

"Yeah, but I think there's a reason for that...you know other than mashing words together. I mean unless there's some sentimental value like Chrismukkah." Ryan replied. He leaned against the fridge. "Dude, are you trying to drown yourself with Coke?"

"Don't insult Chrismukkah." I placed the can down.

"I wasn't." Ryan turned around as he began walking away. "I just think words should make sense."

"It makes perfect sense."

"Sure."

"Like you can do better."

"One month anniversary." He tossed over his shoulder.

Of course, that was the moment my Dad walked in.

"Whose one month anniversary are we talking about?"

"Seth and Summer's." Ryan said.

I scoffed, but then I felt the pain again. "Thanks for telling."

"You would have sooner or later." Ryan shrugged. I couldn't argue with that. He was probably right.

Dad nodded. "Well that's a big deal. What are you planning to do?"

"I was thinking going to a movie then dinner." I took another sip of Coke.

"No no no. You do that every weekend don't you or almost?" Dad asked.

"Well yeah, but Ryan was supposed to help me plan...and I don't have anything better so-."

"Son, last I checked you're dating Summer. What does she like?"

"The Valley." Ryan volunteered. I turned around and looked at him. "What? Marissa told me that she forced her to watch like ten episodes in a row once and wouldn't stop talking about it."

"So you pay attention to that and not…?" I sighed. "Unbelievable. I feel betr…" My voice cracked. "Betrayed."

"Seth," Dad looked at me. "You alright?"

I nodded as I tossed my empty soda can in the sink. I then grabbed a bottle of water. "Nothing a little H2O won't help."

I then walked into the living room and took my spot on the couch grabbing the game controller. "I demand a rematch."

Ryan's POV

"You think that was a smart move?" Seth was goading me, eyes firmly locked on the screen. At least he wasn't talking about Summer this time, but that was odd. Actually, Seth wasn't saying much of anything.

"Better than being out in the open." I replied. I glanced over out of the corner of my eye, and noticed that Seth's hand kept going to his throat. Was he sick? "Pl...planting yourself just means you get stabbed faster." Seth then pushed a few buttons and I heard the cue, but I also heard the cracking

"Guess we're even now." I said. I set the controller aside. "You alright man? I mean you're kind of quiet."

"Aren't you always the one telling me to shut up?" Seth smirked. "You did tune me out earlier."

"That wasn't cool. I get it." I said. "But seriously? No snappy comebacks?"

"You'll hear more about the monthiversary soon enough." He looked over with a grin.

"Looking forward to it." I wasn't sure what I should do. I mean Seth didn't seem concerned about anything...other than the monthiversary, but still...Kirsten and Sandy needed to know about this if he had a sore throat. I'd give it a day. If he was sick, I'm sure we'd hear about it before dinner tomorrow. This was Seth. He'd tell us whether we wanted to know or not. It wasn't my job. Kirsten and Sandy would find out. They were his parents, and parents were supposed to have a sense about this sort of thing. I'd give it a day, and then I'd confront him...and tell Kirsten and Sandy.

A/N: So Seth is experiencing a bit of pain, but he's wrapped up in planning his and Summer's one month anniversary, so he hasn't made it known, but Seth being Seth, it won't stay that way for long.

Please let me know your thoughts. I'd love to know what you think.
