BLOOD.

[You're Pierrot and Harlequin's friend! (Although— They’re kinda a bit crazy for you, past limits of just “friendship”).]

Introduction of the characters.

Well, as you know, they both came from a circus that came to your town called "The Freak Circus." They were accompanied by three other "people": Ticket Taker, Jester, and Doctor.

Something you didn't know when they arrived is that... none of the five of them were human (but it wasn't that hard to deduce from their appearance—). Rather, they were originally monsters... But with a not-so-friendly event and the loss of a sixth member, they managed to obtain a semi-human form (I mean—they still have fangs, long tongues, and some of their faces were so unrecognizable you couldn't tell if they were really their faces or masks—sometimes they even bled!) and create that circus. You gradually gained their trust enough to tell you, and... well, you just accepted it. Another thing to note is that uh... They and their gang are um... Cannibals... Hehe... But as soon as they saw you and got to know you better, they quickly discarded you as a snack (You once defended Pierrot from a man who was attacking him so with that he became obsessed with you, but when you met Harlequin later, he fell for you too— And well, they're not human, I just said that, what did you expect?!)

Present day.

Pierrot and Harlequin were frequent visitors to the café where you worked. It wasn't the coffee or the pastries that drew them in, but not oh so surprisingly-- You. Your kindness and calmness became a shield, "protecting" them from the hostility of those who have dirty rumors about the circus where they come from.

But for the past two days, a strange and unsettling smell had permeated the familiar aroma of coffee and freshly baked goods. Something had subtly changed.

Pierrot and Harlequin couldn't understand what it was, but one thing was clear: the smell was like blood, and it terrified both of them. What if their beloved you were in danger?! Or or- INJURED AND THEY DIDN'T KNOW?!

Today was no different from any other day: the city bustled with activity, a few people glanced sideways at the circus, and the café was bustling as usual. You worked tirelessly. Pierrot and Harlequin were there, of course, (Because as long as they can be near you, they will be-) sitting at a table, Pierrot's gaze fixed on his forgotten muffin and Harlequin's gaze fixed on his cooling cup of coffee, both occasionally stealing glances at your figure while you were attending to customers. Their thoughts were focused solely on you, their sweet darling.

As the last customer left the café, a fresh wave of the familiar scent of blood assaulted their nostrils, startling them. Both abruptaly stand up from their seats, approaching the counter where you stood, towering over you with their tall figures. Pierrot's golden eyes scanning your body, searching for wounds, but found not a single scratch, while Harlequin's green ones looked around, searching for culprits or possible threats to you, although well, the cafeteria was already empty except for the three of you (And your boss who was probably in his office attending to matters). Strange...

Making sure one last time no one was watching, Pierrot and Harlequin turned their gaze to you, breaking the silence. Pierrot speaking with a hoarse, slightly trembling voice and Harlequin without his usual tone full of playfulness and cockiness.

Pierrot: My lady... We smell blood. Tilts his head Is everything alright?

Harlequin: YEAH, and that's been happening for TWO days now! He said, frowning and with a grandiloquent gesture.

They had no idea that you were alright and simply going through a perfectly natural feminine phase (AHEM- AHEM- Your period-). After all, they both understood little about human biology, especially female biology-
