Once again, just like many times before, Marinette found herself with Chat Noir in her bedroom, chatting like the good friends they had become. Their conversations were usually accompanied by some kind of dessert—in this case, cookies—and a glass of milk. However, today was different, and it wasn't because they weren't talking about their problems, how their day had gone, or because the kitty had decided not to make his usual jokes.
It was simply because Chat Noir had gotten a milk mustache and hadn't noticed.
Something unusual, since he normally wiped his mouth with a napkin after every sip in case there were any traces left.
But not today.
Marinette couldn't stop staring at his adorable milk mustache, and it left her completely distracted in the middle of the conversation.
"Are you listening?" the kitty asked, looking at her closely.
"Umm... Ah! Yes, yes," she answered absentmindedly.
"Did you fall in love with me?" he suddenly asked playfully, placing a hand on his chin without taking his eyes off her.
She immediately blushed and quickly denied it, causing the feline to laugh.
"You could've at least hesitated. You're breaking my heart," he replied, pretending to be disappointed as he dramatically placed a hand over his chest.
After his rather elaborate performance, however, Marinette found herself staring at his milk mustache again. She considered telling him about it, but instead she felt an overwhelming urge to laugh, or at least let out a chuckle or grin like an idiot. Because of that, the corners of her lips trembled while her mouth struggled not to form a grin.
"Seriously, Marinette, why are you staring at me?" he asked, watching her with a mixture of confusion and concern. "I know I'm irresistible, but not enough to make you look like that."
"I'm not staring at you," she said, looking away and taking a sip of milk.
"There's something on my face, isn't there?" he asked. Immediately convinced that was the reason, he walked over to a mirror and spotted his "mustache." "When were you planning to tell me I grew a mustache?" he asked with a grin, turning his gaze back to her while reaching for a napkin to wipe it off.
"Sorry, but you were missing the whiskers, kitty."
"You're right about that, My Princess. So tell me, how do I look?" he asked, stopping himself from "shaving" it off.
She smiled and answered the way Chat Noir usually did.
"Purrfect."
The kitty laughed and smiled warmly. Throughout the rest of his visit, he never wiped away his milk mustache. Meanwhile, Marinette kept looking at it, smiling and occasionally holding back laughter because it looked adorable on him.
He was adorable.
And all because he had decided to keep the milk mustache after her comment.
