(FYI, this is gonna be a slight AU. The only difference is, the kids have to wear uniforms to school)

"Today is the day!" Yelled Marinette as she fixed up her hair. Instead of pigtails, she braided her hair neatly. "I'm gonna tell him!"

"What's going on today Marinette?" Asked Tikki.

"I'm going to tell Adrien how I feel today!". Marinette went into the bathroom to get dressed.

Meanwhile, Adrien looked at his reflection sharply. "I'm gonna tell her. I'm going to tell Ladybug how I feel today!" He sternly told himself. He stared at his reflection for a few more minutes before getting ready for school.

Soon, Marinette was ready for school. She was wearing her everyday school uniform. It was a white long sleeved shirt, an off-white jacket with a black collar and cuffs, a black skirt, white knee socks, black loafers, and a black string bowtie. 

(I know it's what Kanade Tachibana wears. I love Angel Beats. I'm working on it right now, so please don't spoil it for me or else!)

Adrien was wearing his everyday uniform. A blue long sleeved shirt, black pants, and black shoes. He felt great about himself.

Later, the 2 teens arrived at school. Marinette saw Adrien, and turned pink.

"Go on!" Alya said, "Go tell him!"

"I can't do it!" Marinette panicked.

"Gurl. You promised me you'd do it today.". Alya pushed Marinette up to Adrien. "Do it!" She whispered to Marinette.

"Hi Adrien!" Said Marinette shakily.

"Oh hello Marinette." Responded Adrien.

"How are you today?"

"I'm actually doing quite well. How about you?"

"I'm great.... Adrien."

"Yes Marinette?"

"I have something I want to tell you."

"Yes?"

"I lo-". Marinette collapsed onto the ground. She felt her senses dying down. She couldn't move for some reason, but felt some sort of liquid running across her body. She saw looks of horror on everyone's faces. She heard people calling out her name, and calling an ambulance. The last thing she heard was Tikki whispering in her ear, "Please wake up Marinette!". Then everything went black.

(Sorry I left you guys with such a sad ending. It'll get better. Trust me. More will be coming soon)
