I think this might be the newest song I have used yet. Could be wrong though, since Monster is a common name for songs apparently, this is the Shawn Mendes and Justin Bieber song. So this in one-shot, Hawkmoth has convinced Paris that Ladybug and Cat Noir are the bad guys, saying that with their miraculous he could grant them all their wishes and that they are being selfish and keeping the power for themselves. So now the people of Paris make it really hard for Ladybug and Cat Noir to do their jobs. Cat Noir, has just given Ladybug his ring back, he can't handle the hatred anymore. So for the last few months Ladybug has been on her own. And in her personal life, Marinette isn't faring much better. In this one-shot, when Marinette snapped at her friends they didn't come back for her. They gave her space and even though they did all forgive each other, the bond was broken, and none of the heroes Ladybug had come to count on were there. So she was truly alone. 

"Tiki, what am I going to do? I need a new Cat! I can't do this without him. And I need to end Hawkmoth soon or else I might just give up. not give the miraculous just disappear for a while and come later." She falls back into her bed. 

"I wouldn't blame you Marinette, this is more than any grade 12 should deal with. You should be planning summer with your friends, picking a college, not taking a year off to work, and watching your friend leave you out more and more." Tiki curled up on her chosen forehead. 

"Hey, at least I got the crazy high school makeover moment." Marinette had changed her Ladybug look to give her jet black hair and ditched the onesie for a more biker chick look, that was black and red, once she started working at night more, helping her blend into the night. When she fought in the day she kept the traditional look. But the jet black hair grew on her, leading her to dye her hair and changing her look, moving to some deep blue ripped jeans, a dark red shirt and a black leather jacket. She had let her Ladybug person show more as Marinette and honestly, it worked for her. 

Sure her friends had started leaving her behind, but she was tied to Paris, and they weren't. She had also pushed them away. Lying had been hard. It broke her, and when Cat left her, well she found a reason to fight harder. She wanted to free everyone from the lies, but these lies cost her partner and she wouldn't let that side. She needed a new partner, it was too hard to do this alone anymore. She stared at the box praying it would give her answers. 

"Mistress, there is one hero you have never asked." Sass, sat on her shoulder. 

"I guess it felt unfair. After how much I hurt him. But I guess it wouldn't hurt." She smile and picked up the bracelet and the ring. "Tiki! Spots on!"  She flew off heading to the apartment Luka had bought last year to work on his music free from his mother and maybe to hide from the world too. She envied him that.  

If she was honest with the Kawmis, she'd gone to his apartment on her nightly patrols since the night Cat quiet. She missed Luka, but it felt wrong to ask so much of him. Normally she sat across the street from him, outsight, but she'd hear him play. He stilled played her song, which made her only feel worse. But she was sure by now he had moved on... But tonight she sat two balconies up and one over from him. He was outside playing like always. 

"Finally got brave enough to get close to me eh Ladybug?" He didn't even lookup. She didn't speak, lowered herself to his balcony. He still said nothing and stood open his balcony door, and let her in. He lit a candle to give them some light. 

"Thank you, I didn't know if you would still believe in me, no one else seems to." She gave him a sad smile. 

"And trust Hawky? Hell no. I was just shocked you didn't come to me sooner. I've seen you stop by every night, it's why I kept playing even after I finished the album." He placed a hand on hers.

"I bought that album. It's amazing. I even bought a disk copy." She smiled. 

"I'm flattered. But I assume you are not here to ask me about an album." He chuckled not moving his hand. 

She to a deep breath, "No, no I'm not. I need your help, Luka. But it's a huge ask." 

"Oh really?" He moved his hand, took a seat on the floor and leaned back. 

"It means your family, friends and girlfriend could hate your alter ego." She sat on the floor and curled into a ball. "And that's not easy."

"One, I live alone, so wouldn't hear it, two my friends are losers anyway." He stuck his tongue out. "And three no girlfriend to speak off. None have been quite right. Guess I can't get my first love out of my heart." he paused, the whispered, "Marinette." 

Her heart stopped for a second for two reasons, one he still loved her? And two, was he telling her the girl's name or calling her by her name? She simply looked up at him with her head tilted and eye brow raised. 

He took her hands, "I'll always be in your corner Melody, with or without your mask." She pulled her close and kissed her. Between kisses, she whispered spots off. "Ah, there's my girl." He smiled as they pulled away. 

"Sorry I made you wait." She handed him the ring and bracelet. 

"I didn't mean to, but I guess once I saw you pull away and change your style I pulled away and couldn't let you be alone. " She pulled her close. 

"I have a plan, now that you are older, you have a new power. The music you make can hypnotize people. Next time Myra comes out to fight we need to use it." They talked late into the night and made plans, and Marinette somehow got her parents to agree that she could move in with Luka. Which improved her mental health a lot. 

They didn't have to wait long, two battles after Viperon joined her team, Myra showed her face. Viperon started playing, and while people came at Ladybug she started to speak. 

You put me on a pedestal and tell me I'm the best
Raise me up into the sky until I'm short of breath

Slowly the people stopped fighting and stood listing to her.

Fill me up with confidence, I say what's in my chest
Spill my words and tear me down until there's nothin' left
Rearrange the pieces just to fit me with the rest,

Viperon jumped down and stood beside her, waiting for the last few fighting to stop moving. And spook with her.

But what if I trip?
What if I fall?

People who seemed to be free from the lying control of Hawkmoth looked down in shame. 

And what if I, what if I sin?
And what if I, what if I break? 
Then am I the monster? 
Just let me know, 

Viperon looked at Myra who was fully under his control, "Take us to Hawkmoth." She did, they followed her to Adrien's home, both heroes gave each other a sad look, and Ladybug knew her guess all those years ago had been right. They went down to his layer. He stood waiting. 

"Ladybug." his voice was curt and short. 

"Gabrial." She shook her head. "I was fifteen when the world put me on a pedestal, I had big dreams of doin' shows and makin' memories." She kicked him, and he was slow to move thanks to Viperon's music. 

"I made some bad moves tryna act cool, upset by they jealousy." She let him hit the grown and Viperon planted a foot firmly on his chest, he wasn't getting up. 

"I was a kid and they lifted me up and you tore me down." She ripped off his miraculous. 

No in his weakened form Garbirel looked to Ladybug and Viperon, "I'll take responsibility for everything I've done, Holdin' it against me like you're the holy one." His words with sharp with venom and sarcasm. Viperon walked over and took Mayra's Miraculous. 

Ladybug looked at them both, her heart heavy for Adrien. Grateful he had taken his aunt's offer to go live with her a few months back. "I had a chip on my shoulder, had to let it go, 'Cause unforgiveness keeps them in control, I came in with good intentions then I let it go." She left them free in the layer. and after the miraculous was back safe in the box she and Viperon let everyone free from their song. And they planed a trip to the temple to return the box to safety.
