Hello, lovelies! So, this is my gift to moonlightusa for uglygreenjacket's UsaMamo Spring Exchange 2020.

I've wanted to write a Disguise Pen fic for a while but just ended up incorporating a whole bunch of fic ideas from everyone on my dashboard lol.

Of course, this isn't finished yet and I will continue to write/update throughout my indefinite quarantine period.

I hope you enjoy it and that it brings a smile to your face during turbulent times! 3

Okay.

So, maybe Usagi shouldn't have insisted she could do this on her own. In her defence, she had just wanted to feel more helpful, to not be dragging Rei and Ami and Luna down. That's why when her middle school had the Friday off for a professional day, instead of sleeping in or spending the day playing video games and eating snacks Usagi proudly and loudly insisted that she could do something as simple as scoping out some fancy-schmancy high school for any signs of youmas.

And here she was, wandering the halls of Moto-Azabu Private High School, totally lost. Hey, it wasn't her fault all the hallways looked the same though. It was like a never-ending maze of pristine tiles and club flyers.

Usagi whined a bit as she tugged at the stiff tie around her neck. Ugh, boys' uniforms were so stuffy; she missed the loose freedom of her skirt and sailor fuku. Although, she will admit that the Disguise Pen did a pretty fabulous job turning her into a teenage boy. Usagi pauses in the hallway, staring at her reflection in a window and running her fingers through her now short hair. While she didn't magically gain any height, the platform shoes the Disguise Pen provided her with at least gave her an extra handful of centimetres. She was cute, all big eyes and soft hair, delicate features with their feminine charm.

"I'm hungry," Usagi pouted as she continued down the near-empty hallway. Not only was she lost, but there were no signs of youma or any dark energy in this place.

"I can't believe I woke up before 8AM for this! Aah! I should just leave and go get something to eat." Usagi kept walking, turning around a corner praying to find an exit when she suddenly realized something.

She was inside an all-boys school. A school full of high school boys.

"Right! I can't waste this opportunity," Usagi whispered to herself, "It's almost lunchtime. I'll grab a snack and then look at all the cute boys before I leave. At least then this day wouldn't be a total waste!"

Usagi leaned against the windowsill, fingers itching to play with long silky hair that was no longer there. She jumped up with excitement when the lunch bell rings, eyes eagerly raking over the stream of students emerging from the classroom, the sound of chattering filling the once quiet halls.

Wow, high school boys were so tall. Usagi couldn't wait until she was done with middle school and middle school boys (yuck).

She pushed herself off the windowsill, humming a tuneless melody as she skipped down the hall.

Usagi's eyes aimlessly wandered around, taking in the foreign sights in hopes of finding a familiar archway or staircase. It's when her eyes briefly flitted over a familiar sight did Usagi stop and come to another realization.

Right. Moto-Azabu Private High School is where he went, how could Usagi have forgotten?

Usagi curiously watched as Chiba Mamoru zipped his bag up, nodding along to something a classmate was saying. The rest of the class emptied out while he lingered behind, looking over a notebook.

Usagi's mind panicked, blaring alarms went off in her head, before she belatedly remembered she was not Tsukino Usagi right now but a nameless male student of Moto-Azabu Private High School. Which meant she was free to continue to stare at Chiba Mamoru's pretty profile and take in his pretty body proportions.

Usagi doesn't know why; maybe it's adrenaline from using the Disguise Pen, maybe it's because Chiba Mamoru looks less like a high school student and more like he's modelling the school uniform with the way he's sitting delicately in the sunlight, or maybe it's because it's weird that even at school he's still got this aura of loneliness clinging to him. But for whatever reason, Usagi found herself stepping into the classroom.

He looked up when Usagi was a few feet away from his desk, the two of them locked eyes with each other.

"...Can I help you?" And, dear god Chiba, are you always this blunt?

"Uh…" Usagi's mind searched for a response because she hadn't really thought this far ahead and her mind ran blank because Chiba Mamoru was really distracting when he was looking right at you like that.

He narrowed his eyes at her a bit, "Do I know you? You—"

"Your eyes!" Usagi blurted, her tongue and brain finally having reconnected. Although that connection wasn't exactly coherent or sensible.

Chiba froze a bit at her outburst, blinking in confusion. "...What?"

"Your eyes are so blue," Usagi continued and leaned in closer because her statement was true and this may be her only opportunity to get a better look at said eyes. "They're not contacts, are they?" She leaned in closer and closer as Chiba Mamoru leaned further back, trying to avoid her dissecting.

"W-what are you—"

"Even your lashes are so long! Unfair!" She was only a few centimetres away from his face now and wow, it's like he has no pores, what the heck?

"People probably tell you you're good looking all the time, huh? You could be like an actor or idol or something with that face alone."

Usagi paused when she noticed the rosy flush spread across Chiba Mamoru's cheekbones, the way he was leaning as far back as humanly possible, lined notebook brought up as a pseudo-shield.

Cute, was the only word that came to her mind.

And of course, that caused a reset of sorts among her neurons because there was no way she just thought that that jerk Chiba Mamoru was cute.

Usagi took another look at how the pink blush on his cheeks and ears contrasted beautifully with the deep blue of Chiba Mamoru's eyes and long, fluttery lashes that peeked out from the top of a flimsy lined notebook that was clutched tightly in between white-knuckles fingers.

Dammit. He was cute. Too cute. Who knew all it took were a few compliments for Chiba Mamoru to get like this?

Wait! No, bad Usagi! She really needed to leave before she did something really stupid, like actually start to like Chiba Mamoru. Yeah, uh... no thanks on that one!

"Well, I gotta go!"

Usagi scrambled backwards, practically running out of the room and then the building, dodging other students and shoving open the first exit door she saw. When she was a street away, hidden between towering buildings, Usagi allowed her disguise to fall, reverting back into average-teenage-girl: Tsukino Usagi.

"That was...something," Usagi blew her bangs off her forehead, hands twisting around the ends of her now long and silky hair. "It was just...the Disguise Pen. Yeah, you just got a little too into it," Usagi continued to console herself as she headed back home.

It's a few hours later and Usagi is done recounting the lack of dark energy found at Moto-Azabu Private High School to Luna, Ami, and Rei. She nursed a tall strawberry milkshake, kicking her legs back and forth leisurely, but her joyful milkshake time was unfortunately interrupted.

"Hey."

Usagi nearly choked on her pastel pink strawberry milkshake when she saw Chiba Mamoru leaning against the counter to her right.

"H-hi," Usagi whipped her head forward, trying her best not to outwardly panic. She slowly turned her head to her left and made eye contact with Rei who stood a few metres away, scrolling through her phone.

Usagi did her best to send a help me! signal with her eyes but Rei, oh lovable Rei, just made a face at Usagi before returning her attention to her phone.

So, Usagi had no choice but to sit there, suffering, as Chiba Mamoru stared into the depths of her very being, drumming his fingers along the countertop of the bar.

"Did you want to order something or…?" Usagi attempted to act casual, 1000% unsure of how to act in this situation, "The strawberry milkshakes are really good."

Is he onto me? Omg why is he just staring? Oh my god he figured out it was me earlier and now he knows what do I do, Luna is going to be so mad! Rei, PLEASE help me.

"Do you have a brother?" He asked instead, eyes narrowed suspiciously at her.

"No!" Usagi practically shouted before she realized oh wait: Shingo… "I mean yes! I do. He's ten and we look nothing alike though, haha."

"Oh," Chiba Mamoru frowns a bit, looking confused and a bit dejected oddly.

"Why are you asking?" Usagi asked, taking another slurp of her milkshake.

"No reason!" Chiba Mamoru jerked away from her, ears flushed a rather impressive shade of red.

He must have really good blood circulation, Usagi thought and thus voiced said thought.

"Your blood circulation is amazing, just look at your cheeks. Brides everywhere must envy you."

And somehow his ears managed to turn even more red. "Whatever," Chiba Mamoru bit out and twisted on his heels, marching away.

Usagi let out a sigh of relief. Alright, secret identity still remains a secret.

"What the hell was that?" Usagi nearly toppled out of her seat when Rei popped up on her other side.

"You scared me!" Usagi whined, clutching her chest.

Rei narrowed her eyes at Usagi as she took a seat on the stool, taking Usagi's straw to pick up some of the remaining whipped cream on the edge of the glass.

"Were you bothering him again?" Rei accused, finishing off the whipped cream.

Yes, and I want to do it again... Usagi groaned, letting her face fall onto her forearms.

"He is always bothering me! Ugh, that was so stressful! I'm never volunteering to be productive again. I need another milkshake."

This is, of course, is set in early season 1/ first arc. I really wish that Mamoru's high school life was explored a bit more lol.

(i usually have more to say in these endnotes but my brain is empty right now oops)

Please leave a comment! They warm my soul!
