Marinette sits down on her lounge, remembering what happened earlier that day.

"Lila's not hurting anyone."

"She's hurting me, Adrien!"

"But you're strong, Marinette. You can take it. They can't."

"I can't take it forever! She's threatened me!"

"Lila wouldn't do that."

"You'd believe that liar over one of your best friends?!"

"You have to take the high road, Marinette."

"... I hate you, Adrien."

Marinette looks at her wall full of Adrien's pictures and the pictures of her classmates, then tears them down, angry. She throws the pictures behind her, crying. She throws them in a trashcan, lights a match, and throws it in the can, watching all the pictures burning.

"Why, Adrien? Alya, Nino, Alix, Kim, Sabrina, I did everything for you, and you do THIS to me?" She growls.

Tikki nods, angry herself.

"It's kinda like I'm trapped and can't escape, Tikki." Marinette whispers.

Tikki sighs, "He chose this."

"It's sad how he decided this was our fate." Marinette whispers.

As the last picture of Adrien and the class burns, a purple Akuma absorbs into her bag.

"Poor, broken child, I am Hawk Moth. I can give you the power to show your foolish class the truth. All you have to do in return is bring me Ladybug and Cat Noir's Miraculous. Do we have a deal?"

Marinette pulls off her earrings, flinging them onto her bed.

"I'm feeling cold and dead inside, Hawkmoth. We have a deal."

Marinette looks up, a purple fog forming around her. Her hair turns white as snow, her face porcelain, her torso, clear as glass, her heart as hard as a rock, a picture of a broken heart of glass on her arms and legs, which are blue and green.

"Now my heart's turned into stone... I'll be better off alone after I deal with my traitorous friends." She glares.

She jumps out of her room onto her balcony, then jumps down to the sidewalk, landing with a thud. She walks to the school, where everyone from her class is still hanging out. Until they see her. They start screaming, running. Marinette smirks, her normally bluebell eyes glowing red. She manages to herd them into a classroom, Bustier there too. She locks eyes with Lila, who panics and runs. Marinette's arm snaps off like a glass doll and starts chasing after Lila. It grabs her and drags her back to the classroom.

"So, you're all here. Adrien, Lila, Alya, Nino, everyone. Can anyone guess who I am?" Marinette smirks.

Everyone shakes their heads, confused.

"Let's see if these words ring a bell for anyone. "Isn't Jagged Stone's pet a crocodile?" "Can you confirm she doesn't know ladybug?" "I only tell people what they want to hear." "It's obvious she doesn't have a sprained wrist!" "If you humiliate her, she'll just be hurt more." "Lila isn't hurting anyone." Ha! I can't believe you all."

Someone gasps, "Marinette?"

Marinette laughs, "Not anymore. See my heart inside my chest? The stone heart? And the broken heart of glass on my arms and legs? I am the Heartstone. And my heart is broken by all of you."

She then starts singing, "All I feel is hate!

Kinda like I'm trapped and can't escape

You've cut my wings and locked me in a cage

It's sad how you decided our fates

I'm feeling cold and dead inside

Just can't get you off my mind

Now my heart turned into stone

Guess that I'll be better off alone.

I don't know if my heart can ever be unbroken

If there's someone who can pick up all the parts

And even though I'm breathing, I am choking

As I try to glue together all the shards.

I wish my heart would be unbroken

Unbroken

Unbroken now

I wish my heart would be unbroken

Unbroken

Unbroken now

Unbroken...

All I feel is pain

As if I got run over by a train.

The situation's messing with my brain

Because you got me shackled like a chain.

I'm feeling cold and dead inside

Just can't get you off my mind

Now my heart turned into stone

Guess that I'll be better off alone.

I don't know if my heart can ever be unbroken

If there's someone who can pick up all the parts

And even though I'm breathing, I am choking

As I try to glue together all the shards.

I wish my heart would be unbroken

Unbroken

Unbroken now

I wish my heart would be unbroken

Unbroken

Unbroken now."
