"So who was he? The boy you loved so much."

It was evening at the Eiffel Tower, and Chat Noir sat and leaned against a beam. The weather was clear, the sunset was golden, and Ladybug was curled up in his lap, lazing against his chest as he traced his claws across her stomach.

They'd gone on several dates in the last few weeks, and he thought it might be safe enough to finally satisfy his curiosity.

She didn't answer immediately, just hummed absently while she considered. "I finally got over him enough to see what was right in front of me this whole time."

Chat Noir felt his face flush. It might have embarrassed him a few weeks ago to display how easily she made him swoon, but he didn't bother to hide it now.

"It would compromise my identity," she said, "but I don't really care anymore."

He nodded, and his hold on her tightened. That was so much more than he had ever expected and wished for.

Ladybug launched into an explanation. "Okay, so do you remember that first year we fought together? How Chloe's class got akumatized a lot?"

"Almost everyone in the class got it at least once."

"Right. I was in that class. And so was the boy I was crushing on."

Chat was intensely interested, leaning forward and shifting her in his lap.

"I'm explaining this to you," she continued, "so you don't make fun of me."

"Why would I?"

"Because." She let go of him to hug herself. "I'm not like all the other thousands of girls who had a crush on Adrien Agreste. I personally knew him. We were close friends back then."

His breath caught at his own name, and it took several seconds for it to return to a normal pace. He wasn't sure his heart would ever calm down. Not only did she love him now, but she had loved him the entire time.

That also narrowed down the list of people she could be. It had been several years, but he still remembered the roster. Chloe, Lila, Alya, Rose… all those girls he knew couldn't have been Ladybug. They'd been heroes and villains he and Ladybug had fought either with or against. Their looks were didn't match, their personalities were too different, and he ruled them all out one by one, until–

"I hate to give you bad news," he said after several seconds of recovery, "but I know who you are."

She shrugged, leaning against him again. "I figured you would. You got to know my class well after a year of fighting them."

"More bad news." He swallowed around the heart beating in his throat. "You didn't get over Adrien."

"I did!" she said, jerking backward. "I love you! More than anything." Her eyes were wide and insistent, begging him to believe. "I love you with my whole heart. You're the only person for me. I love only you, I mean it. Why– Why are you smiling?"

"Because you're lying."

Her face flooded red, like she'd just cast her Miraculous Cure. And just like the real Cure, Chat Noir was left with the feeling that everything was right where it should be, and safe, and whole. When he cupped her face, she grabbed his wrists to steady herself.

"You love Adrien," he said, a smile coloring his words. "More than anything."

She opened her mouth to protest, but he cut her off with a kiss to the cheek. When he pulled away, her face was scrunched in confusion.

"You love Adrien with your whole heart." A kiss on the opposite cheek.

Her expression was unwinding, growing loose with what he hoped was comprehension. He waited, holding her. This time, he was the one silently begging the other to believe.

"Adrien is the only person for you." He kissed her on the nose.

Ladybug - Marinette - didn't let him get far, holding onto his neck to keep him in place. Are you serious? her expression asked him. You're not making fun of me right now?

He let his wide smile answer, and one more repeated line. "You love only Adrien, I mean it."

Chat Noir leaned in one more time, kissing her smiling lips. When he pulled away, he found himself wrapped tightly around her and encircled in her arms. Just where he'd always wanted to be.

"That's what I said," she replied. "I love you, Adrien."

THE END

Author's note: Thank you for reading! I loved working on this story. When I started, I literally asked myself the question, "How obvious can I make it before he catches on?" and it was so fun to write him being super dumb about everything!

Special thanks to my betas, Jennagrins, sunnywet, and missnoodles. You made the story stronger, and I'm grateful!

(Self promo warning) Check out my profile for my other stories. (Lots of one-shots and a handful of longer stories.) Be on the lookout for my Square Dance fic in Nov. and my Big Bang in Jan. I've also got a ton of drabbles that I have ideas for, plus a few one-shots and longer fics that I'm excited to work on!
