Adrien was usually really good at keeping his emotions in check. Cool, laid-back model citizen.

But when he saw Marinette with Nathaniel, he felt his chest tighten, his hands shake, and felt hatred swell up in his chest.

If that wasn't out-of-control jealousy, nothing was.

"So... If I write 'Lady Macbeth's mental demanour changes drastically throughout the play...' I should get higher marks than by saying 'Lady Macbeth is a crazy old woman when she realises she's a crazy dark hearted woman'?'" Marinette asked, raising an eyebrow. Nathaniel laughed, smiling.

"Yep, that's about right, Marinette."

"I have it in the bag, then." She grinned.

"Yeah, you do." He answered, handing her the copy of 'Macbeth', "good luck tomorrow."

"Thanks." She smiled, placing the book in her bag, "I'm probably going to need it."

"You'll do fine." She left the library, thinking she had been completely alone with Nathaniel.

She had no idea Adrien was watching.

"Marinette isn't cheating on you, Adrien." Plagg rolled his eyes at the boy, "you're being insecure. Maybe if you told her it was Adrien underneath the mask, she'd flip for you even more."

"I can't tell her. Bad guys'd use her to their advantage. Hawkmoth could find out who I am."

"One; you have overactive imagination. Two; you really think she'd bait you out?''

"No." Adrien sighed, closing his eyes, "I don't want to lose her, is all." He looked at his ring, biting his cheek. He knew it was probably wrong to tranform for fear of losing his girlfriend, but he needed to know she was his.

"You're going to tranform, aren't you?" The cat-like creature asked, sighing.

"You got it," The boy answered, "Plagg, claws out!"

Marinette was in bed, sniffing, when he found her in her. Chat looked at her, his eyebrow raised.

"Nathaniel." He said, as soon as he climbed in the room, "what were you doing with him?"

"Not now, Chat. I'm ill."

"Answer me." He persisted, looking directly at her. Her eyes darted to the bag.

He must've missed something.

"N-nothing." She sneezed into her hand, wiping her nose with her sleeve.

"Don't lie to me." He whispered, his voice low and dangerous. His princess rolled her eyes, and crossed her arms.

"I like you, not Nathaniel, you silly kitty." She answered, pulling the covers over her more. He moved closer, his lips brushing her ear. Now, she felt slightly intimidated. He leaned over her, and looked at her with menacing eyes.

"You're insulting my intelligence."

"No, I'm not. Look, we were studying-"

"I saw that." She gaped at him, and she moved away from him. He stared at her, and she flinched.

He was scaring her. "Now answer me. What's in the bag?"

"Uh, I- Chat, I-"

"Please, Mari, I'm losing my patience." He growled, hitting the wall with his fist.

"Chat, you're scaring me." She whimpered, sniffing.

Her eyes, her beautiful bluebell eyes, were full of fear and fright.

He was scaring her.

Automatically, he pulled her close, rubbing her back soothingly. She didn't say anything, just kept quiet. He ran his fingers through her hair, gently whispering apologies in her ear. Her hands gripped the back of his suit, pulling him closer. Then she spoke softly.

"The... Thing, you were talking about, it's in my bag." She whispered softly, "It's a box of chocolate hearts, from... Nathaniel. But don't hurt him! He was only being friendly!"

"I won't hurt him."

"Promise?" She asked, holding on to him.

"I promise, Princess." He kissed her forehead.

"I care about you, Chat, but.. I would never... y'know."

"I know, I should've known, I was just... over reacting."

"Maybe just a little."

"Yeah," He cradled her head in his arms, "Let's get you to bed."

He made her soup, fed it to her, and sang softly to her.

The things he only did for Marinette.

No other girl.

She sat there, content, letting him pamper her. He held her close, kissed her, told her she was his, and he was hers. They were happy. She only needed his company. The girl was sleeping in his arms when Chat had to leave. He crawled up the stairs, standing on the roof. A man, wearing a silver fox outfit, stood facing Paris.

"It's beautiful."

"Like many things." Chat answered easily, "but not you."

"You hate me. That's why I haven't come out as Silver Heart yet. Ladybug would never work with me."

"Ladybug would never work with you anyways."

"Why?" The man turned around.

"Look, Silver, it wouldn't work."

"No?" He asked, laughter evident in his voice. Chat scowled, narrowing his eyes at the 'hero' and growling. "Why not? Because you wouldn't allow it to work? Because you'd bully me into submission? If I told Ladybug that, would she want to work with you?"

"She wouldn't believe you."

"But she'd see one look on your face and know I was telling the truth. Tomorrow, I am coming out as Silver Heart, and you can't stop me. Or I tell your 'princess' what beast she's really dealing with." Silver Heart answered, his eyes gleaming. Chat glared at the other man, breathing heavily. "I won't screw with your girl. That was all a joke, kitty-cat. Chill."

"It better be a joke, because if I find out you've touched her, you'll figure out how it feels to have my power used on you. Let me assure you, it burns like hell." Chat threatened.

"I said I won't touch your girl."

"Or Ladybug. She's like a sister to me."

"Do I get any of the good looking ones?" Silver asked, teasingly. Chat clenched his fists, trying to ignore the hero. He heard Marinette stepping up to the rooftop.

"You OK?" She asked, leaning up to kiss his cheek.

"Yeah. I'm fine." He replied, staring at the sky.

There was no trace of Silver Heart anywhere.

"OK, Chat, if you're sure. Come back in, it's freezing up here." Huh, he thought, I never realised how cold it gets when he's around. Maybe it's just me.

"Sure, princess." He came back down, lying next to her. She fell back asleep quickly.

But he stayed awake, thinking about the Silver Heart.

And praying he was true to his word over Ladybug and Marinette
