Well, time for another big award show speech. I started this story a whole year and a half ago. Not to mention the idea was so random and out of nowhere. But, you guys actually encouraged me to continue. The fact that this is on the first page for reviews, AND favorites, AND follows, is just awesome. And, I really love it. It's even fun for me to go back and re-read. I wish I could thank everyone, but that's so impossible, since there's SO many of you. Thanks to everyone who favorited, followed, or just stopped by. Then, thanks to all the guests, who really helped this story reach so many reviews. Thank you guys for loving everything from the jokes to the scenes to the characters to the wording. Thank you to everybody who laughed at my attempts at humor, everybody who got so emotionally involved that they've been yelling at the characters, everybody who stayed up all night to finish it, everybody who converted to Ferbella, and everybody who just fell in love with the story. I love you all. I pray my ending can meet your expectations. Who knows, this might not be the last you see of the String Theory cast. And please, if you liked String Theory, follow me and read what else I can write!

Lots of love, Silver

Work has turned into just that. Work. It's never fun. Phineas was right. It had turned into just a back and forth routine for me. Dull, but at least it wasn't risky. I don't think I'll ever take another risk again. Agreeing to friends-with-benefits… that was the stupidest thing I've ever done. And far too risky. I risked every relationship I had, and I think I came out a loser. I can't believe this is happening. I'm an idiot. Can everybody agree on that by now? I had SO many chances to admit I loved Isabella, and I barely admitted it to myself.

I glanced out my office window. It was absolutely wretched outside, pouring rain. I didn't ask for it. Any of it. At least, I don't think I did. But, maybe I should have just left her to "rot in her own misery". Maybe picking her off the ground was asking for it.

"Please, please, let me in!" I heard a girl desperately cry. At least with our two offices, Phineas', and mine, random people were kept out by security. But, my office had partially glass walls, and I could see a drenched black-haired girl, begging to come in.

"You can't just storm into Mr. Fletcher's office."

She begged in desperation. "No, please, he knows me, I'm Isabella."

My stomach twisted into a little knot. There was that part of me that said, "Heartbreaker," in a malicious tone, as I looked at her. "Don't let her in." Then, there was the rest of me. That stupid, and overwhelmingly larger, part that is, and always would be, completely in love with her. So I opened my door.

"Ferb!" She ran to me.

I put up one hand to let security know she was fine, then let her in. I leaned against my desk, crossed my arms, and stared stonily at her. Isabella, with her wet sweatshirt, jeans, and mess of hair looked so different from me in my stiff business clothes. She bit at her lip, and I felt weak again. She didn't seem to know what to say.

"Ferb…" She began.

"Don't." I muttered. I turned my head.

"No! Please, baby!" She sounded very upset. "I ran here in the rain! From my apartment! In these same fucking SKINNY JEANS!" She stomped her foot. I realized she was, in fact, wearing those jeans that I think I've become fond of, no matter how hard they are to get off her body.

"What do you have to say to me, Isabella?" I asked.

"Umm… Je te désire. Tu es l'amour de ma vie."

That exact statement took me by surprise. Just the fact that she remembered something like that, and held on to it all this time.

"I want you. I love you. I always thought I knew what I wanted. Who I wanted to be with. Who I even was." I saw she was beginning to blubber. "I've… I've made so many mistakes, Ferb. Because you've always given me everything, and you're always been there, and I was stupid enough to push you away. So many times. And I… I love you. I thought I knew what that meant and I didn't. I wouldn't, without you. And... and... why aren't you saying anything, you jerk? You like listening to me stammer like a fool?"

I caught her around the waist. Finally. Because I am completely meant to fit with Isabella. We were pressed so close together. She wrapped her hands around my neck. Our noses rubbed together, and I gently brushed my lips against hers.

"Darling," I murmured. "The one question everyone has been asking me since this whole thing began was, how long? How long have you been in love with Isabella? And I kept telling them, and myself, that I wasn't. Then, that it was a newfound emotion. But, now I know… I've always loved you. And that's why I've always tried to keep the smile on your face." I said. "No matter how stupid you are sometimes."

She momentarily feigned anger, but I could tell she didn't mean it. "And you told me." She said gratefully.

"I've been dying to tell you." I confessed.

"It feels like one of those 'Finally!' moments." She said.

"Finally." I said in a low voice. I pulled her fully against me and kissed her. Oh thank god, finally. My lips moving against hers, my tongue re-exploring her mouth, and the delicious moans we make between every new breath of air; I missed it. I hoisted one leg up and she wrapped it around my waist. All I wanted to do was put her down on my desk and do wicked things to her.

She started laughing. "Ferb, this is your office!" She scolded.

"Love, that is just what you do to me." I moaned in mild distress.

"Well, when we get home, you'll get to do anything you want to me. Anything." Isabella said naughtily.

"I think it'll be worth the wait." I replied.

"Oh, I love you." She moaned. "I love you. I love you so much." She said sweetly. "And it's finally going to be more than just… friends with benefits. More than just friends."

I clutched her hand and kissed it. "So what am I now, Bella?"

"Well," She said thoughtfully. "I'm pretty damn sure I want you to be my boyfriend."

"Well, Isabella," I said. "I believe we could make this work. With some ground rules."

She threw her head back and laughed. "Right," She tangled her hands up in my hair. "Rule 1: We tell everybody, so everybody knows that you and I are off the market."

"Agreed. Rule 2: We do everything perfect couples do. We celebrate birthdays and anniversaries, we go on plenty of dates, and you let me pay for you." I said. "And, obviously sex. The sex is nice."

She giggled again. "Rule 3: You are absolutely and completely mine. As in you can beat up guys you're jealous of and I can drop kick any chick who flirts with you." This time I laughed. "Okay, that might be a bit extreme, but I don't ever want to hear the phrase 'no strings attached' again. Ever!"

I brushed some hair out of her face. "And rule 4: I love you, Isabella. No matter what."

"I love you too." She said breathlessly.

And I kissed her. Theoretically, none of it made sense. It was passionate and crazy and completely out of character for the "real" Isabella and Ferb. But that didn't even matter. Because, I've theorized that maybe we really are the perfect couple. And it's time to test the theory out.

Update 1/4/17: Officially, this story you guys made so popular now has a sequel. Grand Unification Theory. Check it out. Bye.
