Marinette had had an exhausting day. She had baked seventy two cookies and two cakes. One was mango mousse cake. Another was strawberry mousse cake. Lately they had been making lots of mousse cake. It was the new flavor and lots of people loved it. 

But Marinette was Marinette. She didn't even know mousse existed in the bakery yet. So when a customer asked for mousse cake, she screamed and thought he was saying moose cake. And that alarmed him, the shop, and her parents.

When he smelled it out, Marinette screamed even louder. Mouse cake? EW! Who in the world would eat that? Would she have to kill a mouse and - her face turned green at the thought and she didn't get to finish it.

Luckily, it turned out he just had very bad spelling and forgot the extra s. Marinette was so humiliated she stuttered - no surprise there - and ran of muttering she had an urgent appointment with the toilet she forgot about.

Instead of going to the toilet, she ran to her room and threw a pity party for herself. And after Tikki told her a hundred and fifteen times to go help her parents (not that she was counting), she finally, reluctantly, headed down to the bakery again to face the scowling customers. Apparently, they could still  hear the ringing of Marinette's screams in their ears. A little after-effect, that's all.

For the rest of the day she kept her head down, avoiding her parents' disapproving faces behind the fake smiles that didn't quite reach their eyes and the customers' faces at all. She baked. Baked. Baked. She baked some more. And  baked. Baked. Baked.

Until she was drained and slumped onto her bed. The moment her pillow hit the bed, she fell asleep.

She was about to snore when there were screams. High-pitched, blood-curdling screams. She assumed it was just her remembering the embarrassing screaming incident today. Or nightmaring herself dropping a mouse - mousse cake - on the floor after so much effort and time and feeling like she was going to break into a million pieces.

But then there were shouts too, and people saying REALLY LOUDLY "HELP!"

"Hmph," she grumbled. "Who's interrupting my snoring?" Then someone called, "Ladybug! Chat Noir! He-"

Her eyes popped open and she scrambled outside, slipping on her slippers and hurrying outside at breakneck speed.

She didn't even care that she was still in her pijamas. A little boy stared at her as he walked by, and she rolled her eyes at the judgemental look on his face.

Surely he wouldn't be thinking, Oh, that's Ladybug in her pijamas, ready to save the day!

Her face turned serious. There was nothing outside but everyone was scurrying away to seek shelter and lock the door. 

Scurrying like mice.

Stop thinking about that!

Marinette heard footsteps. Oh no. Her parents must be awake! She quickly went up the stairs and pretended to be sleeping all along. When her parents opened her door, she was already "sound asleep".

Unfortunately, Adrien wasn't that lucky.
