Third Person POV

Marinette groaned as she rolled over in bed, slamming the snooze button on her alarm clock. She was just beginning to doze off when her arm fell off her alarm clock, hitting the metal frame of her bed. HARD.

"Ouch," she screamed as she jumped up in her bed, only to notice she was sitting in a giant splotch of red. She started feeling bloated and moody yesterday, but she hadn't thought that her period would have come so soon.

I guess I'm gonna have to change my sheets Marinette thought to herself, mentally and physically sighing in the process.

Marinette already knew this was going to be a pretty shitty day, especially since she had patrol duty tonight. Not to mention that there could be an akuma attack at any time. And, to top all that off, she had to endure a whole day of school trying not to fall asleep during classes, having to put up with Chloe's bullshit, and feeling like crap ( most likely looking like crap as well) in front of the boy she had fallen head over heels for: Adrien.

She knew that Adrien wouldn't judge her (he was a super kind and caring person after all) but she still wanted to be the best person she could on front of him; and possibly one day, by his side.

She groaned at the thought of school and rolled out of her bed. She trudged over to he closet and picked out her period outfit that served as a warning to Alya; light grey sweatpants that cinch at the ankles, with a plain baby blue short sleeved t-shirt, and a pair of brown Ugg ankle booties that are rolled down to show the furry insides.

Once she had picked out her clothes for the day and got dressed, she went into her personal bathroom that was attached to her room, and looked in the cabinets underneath the sink. She groaned as she looked at the bare shelf, and realized she forgot to stock up on pads and tampons.Looks like I'll just have to use toilet paper then. She stuffed the toilet paper into her panties shamefully, and headed off to school, praying that the toilet paper wouldn't leak.

When Alya spotted Marinette at the front gate of their school, she gave her a sympathetic look. Alya ran up to Marinette and assured her that "Everything is gonna be fine girl." Marinette sighed in relief as she walked with Alya to their first class of the long day to come.

The first thing Marinette noticed as she entered the classroom was how sexy Adrien looked. This made her feel super self conscious of her sloppy attire. She nervously walked up the steps to her seat, right behind the beautiful boy.

One of the many reasons why she loved sitting in the back of Adrien is that she could lean in and smell his amazing scent, without being considered suspicious or weird. Another reason why she loved being behind him, is that she could watch the back of him all class and see all the cute little things he does; slightly nodding his head at certain points in the lesson, rolling his pencil between his thumb and pointer finger when he was trying to think, rolling his shoulders back when he was starting to get bored, and so much more. Noticing all the little things made her fall for Adrien even more, and it brightened her mood during class.

But with ten minutes left in her hour and a half class, she could feel her pants become soaked with blood. And, she could feel some dripping down her leg. She looked down with dread and felt mortified when she saw how noticeable it was. She raised her hand nervously and the teacher signaled for Marinette to ask her question.

"U-um can I please go to the...n-nurses office...?" Out of embarrassment she trailed off at certain points, but the teacher understood.

She said, "Yes Marinette". Marinette got up awkwardly and tried to walk down the stairs and outside without showing any of the damage. She would have been successful in keeping her dilemma to herself if it weren't for Chloe.

Chloe had been in an especially bad mood that day, and felt like being a bitch, especially to Marinette. "Ewwww...Marinette's are all bloody...Why don't you try birth control sweetheart?" Chloe sneered. Marinette froze on the stairs, her face turning a deep shade of red. Her eyes began forming tears and she lost the ability to form words.

Alya looked like she was going to kill Chloe, as did Nino. The teacher looked appalled. The rest of the class were shocked and didn't know how to respond. But Adrien simply walked up to their teacher and whispered something in her ear. She nodded and he walked towards Marinette.

Adrien took off his sweatshirt and presented it to Marinette. She unfroze, and tied his zip-up around her waist. He put his arm around her shoulder, glared at Chloe, and proceeded to escort Marinette, our lovely Ladybug, out of the room. Everyone in the class was left awestruck, including the teacher. But after a minute, everyone resumed what they were doing before the incident.

Out in the hallway, Marinette began to cry, throwing Adrien off-guard. He let go of her shoulder and then pulled her into his arms. Marinette was so shocked that she didn't do anything at first. Then, she suddenly hugged Adrien super tight and started weeping in his arms, surprising Adrien immensely.

He thought that she still didn't like him very much after she thought he was putting gum on her seat, when he was actually trying to remove it. Adrien held onto her tighter. And they finally let go when Marinette stopped crying.

That's when she decided she had to do something now. "Adrien, I know I'm only going to have the courage to say this right now," she said looking directly into his light green eyes. "I like you Adrien," Marinette said just before the bell rang.
