A/N While I'm working on a new request here's a cute little one-shot that I couldn't get out of my head. Also I did upload chapter six with an entirely new plot so go check that out. Well I don't own Fairy Tail… enjoy!

Le Potato: That was the sweetest review ever thank you so much! Do you happen to have an account on this site? You seem so nice and adorable (sorry if that sounded weird lol)

Prompt: Two teachers are dating but one of them is a sub so they always have free time and spend their free periods in the other teacher's classroom. But wait no one is supposed to know they're dating whoops. Adapted from shittyaus on tumblr (psst go check out their blog its great)

"Hey Wendy!" Chelia called out from down the long hallway. Wendy paused and turned to wait for her best friend to catch up in the crowded hallways.

"Hello Chelia. Are you excited for Ms. Lucy's lecture today? I've never seen you walk so fast on your way to class." Wendy teased before picking up the pace again.

"Of course not! Ms. Lucy is a nice teacher and all but I hate lectures. I'm excited to test one of my theories!" Chelia grinned manically and Wendy had to suppress a shudder. Her best friend was downright terrifying sometimes. Especially when it came to her theories.

"What are you testing today?" Wendy asked cautiously. Honestly she wasn't even sure if she wanted to know.

"Well you know how the metalworking is never in class during fourth period?" Chelia asked while bouncing on the balls of her feet.

"Yeah isn't that because Mr. Redfox goes to talk to the head librarian?" Wendy tried to remember the rumor that had been going around but couldn't. Maybe it was due to her latest cram session which had her remembering nothing except for biomolecules.

"Correct! It turns out that Levy called in sick today." Chelia said.

"Why does that mater?" Wendy asked. The warning bell rang and Wendy had to stop herself from huffing impatiently. They were going to be late for Ms. Lucy's class at this point!

"It matters because other classes have been whispering about where the substitute teacher goes when he isn't teaching. Apparently he goes to Ms. Lucy's room because they're dating!" Chelia said and then quickly scanned the halls as if the substitute was going to get her.

"I can't believe that Cobra would be dating Ms. Lucy." Wendy said while shaking her head. "She's so happy and bubbly while he's…kind of scary." Wendy continued in a low whisper.

"Opposites attract!" Chelia trilled. "Besides it's just a rumor. My theory is that everyone is right. Since we have fourth period then if the rumor is true Cobra should be in our class."

"We also should be in our class. The late bell is about to ring so let's go." Wendy squeaked once she saw the time. The two girls began a mad dash towards Ms. Lucy's AP English classroom and passed through the doorway right as the bell rang.

"Glad to see you two! Come on in and take a seat!" Lucy smiled warmly at the girls as they shuffled towards their spots in the back of the class.

"I don't see Cobra. Maybe everyone was wrong." Chelia sighed and slumped down in her chair. Since Wendy was her desk partner, the blue haired girl could reach over and comfortingly pat Chelia's back.

"Sometimes rumors are just rumors." Wendy said softly before pulling out her notebook to prepare of the lecture. About five minutes into class, with Chela still bent over in denial, someone opened the door. Wendy looked up from the sentence she was writing and almost dropped her pencil. It took three harsh jabs to Chelia's side before the other girl would look up.

"What is it Wendy?" Chelia hissed but all Wendy could do was point towards the door. Walking through the doorway and into the classroom was none other than Cobra.

"He's here!" Wendy whispered urgently.

"Are the rumors right?" Chelia whispered back.

"Erik what are you doing? Aren't you covering for Gajeel this class period?" Lucy asked with a glance at her class. Everyone was staring at the pair with confusion, or amusement if they were as well informed as Chelia, and Lucy laughed nervously.

"Erik?! I thought his name really was Cobra." Wendy said in disbelief.

"Do you know who knows people's real names? Their significant other. I can't believe the rumors are true!" Chelia was overcome with excitement at the new turn of events.

"Class why don't I must give you this time to work on your midterm projects?" Lucy asked the class and the procrastinators, which is a majority of the students, agreed enthusiastically. Reluctantly Wendy and Chelia also pulled out their materials to work but not without sneaking glances at their teachers' interactions. At first Lucy seemed to be scolding Erik but then the pair began exchanging friendly banter.

"They're so dating!" Chelia screeched and accidently flung her pencil across the room.

"Maybe they are just really good friends." Wendy suggested while placing another pencil in Chelia's hands.

"No. Ms. Lucy and Coach Dragneel are really close friends. Secretary Mira and Nurse Scarlet are really good friends. Ms. Lucy and Cobra are a couple!" Chelia defended her point. Several classmates looked over at the pair and so did Ms. Lucy. Their poor teacher couldn't cover her blush quickly enough and the two saw.

"I told you that it was too obvious switch you always in my classroom!" Lucy said to Erik.

"Actually Ms. Heartfillia," Erik said, using Lucy's professional title, "they wouldn't have known for sure if you didn't just say that." Lucy sighed in defeat while her students began cheering.

"Everyone please stop cheering! We don't want Mr. Fullbuster's geometry class to get interrupted." Lucy pleaded but the students kept clapping and hollering.

"Oi you idiots! Shut up. I'm not on duty right now but I'm not above signing detention slips." Cobra grinned deviously before Lucy smacked him.

"I'll just make sure you're on detention duty that day then. No giving out slips to my students." Lucy reprimanded and he sighed but put his hands up in surrender anyways. Watching them eagerly was Chelia.

"Now that I know they're dating I have a new theory!" Chelia said to Wendy.

"What's your new theory?" Wendy asked. It was bad when Chelia got a theory but it was even worse when she got another one immediately after another.

"That they've eloped already and are secretly married!" Chelia grinned. All Wendy did was flick her on the forehead. "Ouch! What was that for?" Chelia frowned and rubbed her forehead.

"Stop imagining our teachers our married. Dating is one thing but marriage is too far, even for your creepy mind." Wendy replied casually.

"Hey! Don't be so mean." Chelia pouted. Wendy clicked her tongue and shook her head in disappointment. Hopefully one day Chelia would learn to get over her radical shipping tendencies. Probably not considering who she's related to.

What a shame.

A/N I planned for it to be a CoLu thingy through the eyes of someone else (because I can't write Cobra's perspective for shit) but I think it turned out to be more of a Wendy/Chelia friendship fluff au. Whoospies :P. Also I know I switched between Cobra and Erik as names but that's because I was assuming he'd want his students to call him Cobra (his alias) while Lucy (who has earned his trust) gets to call Erik his real name. Idk just my perspective lol. Well that's all so thanks for reading!
