[Reminder: This story is ten years in the future. So sorta like the Act Your Age episode but a few more years. Also forget that Phinbella gets together in Act Your Age as they are already together when they are thirteen. At least in my story they did >^<
Ferb and the gang: 23
Vanessa and the other teens: 26]

No one's P.O.V

This was a big day for small-town, Danville boy, Ferbs Fletcher.

It was his wedding day. The happiest day of his life. He was getting married to the girl of his dreams, Vanessa Doofenshmirtz. Soon to be Vanessa Fletcher. Yet, all he felt was butterflies in his stomach.

"Ferb, you'll be fine!" Ferb's step-brother, Phineas, whispered.
"Easy for you to say. You're not the one getting married." Ferb said.
"You don't want to get married?" Phineas asked.
"I do! It's just...what if Vanessa backs out? What if she doesn't want to get married? What if Monty and Johnny come back and she likes them more than me? What if..." Ferb said.
"Whoa, whoa, Ferb. Calm down! None of those things will happen." Phineas assured his brother.

Suddenly, the wedding march started playing and Phineas' Mexican-Jewish girlfriend, Isabella Garcia-Shapiro, started walking down the aisle with a bouquet of pink roses.

Phineas' eyes resembled hearts as she walked closer and closer. They watched as the flower girls in front of Isabella threw around flower petals. They were all wearing pink and white dresses as they skipped towards Phineas and Ferb and Ferb's groomsmen, Buford, Baljeet, Jeremy, Coltrane, and Django.

"Hey, Phineas. Ferb, you look great." Isabella said as she passed them and walked to the bride's side of the altar.

The rest of the Firseside Girls alumni followed Isabella. Candace and Stacey walked down the aisle, too. Although they were both happily married, they were still excited about being bridesmaids and acted just like they did as teenagers.

"Good luck, Ferb." They whispered and stood next to the alumnus.

Ferb's butterflies got stronger when Vanessa didn't appear. After a few minutes, he started to get worried and was about to full on panic when Vanessa finally appeared.

His butterflies disappeared and his heart beat faster, just as it did the first day he met her in the blueprints shop.

All he could think about was all the memories they had shared. When he met her, when they were in Paris, when he helped her in the Supermarket, and most importantly, the ray that changed their lives. He thanked Phineas everyday for that machine that brought him and Vanessa together. If it wasn't for that ray, they might've never even spoken or Vanessa would never had noticed him that way.

Vanessa walked closer to him and he beamed. She was wearing a white dress that was similar to the black one that she'd worn on their first date. Their families had agreed to let them date after that. He had Candace to thank for that. Candace had planned on being a lawyer so having a great arguer like Candace on his side really helped.

He was thankful to everyone. They had all helped in their own weird way. Even Monty and Johnny, although Ferb still didn't like Johnny near Vanessa as Johnny was still obsessed with her.

Ferb and Monty were friends though, since he got married to a Canadian agent named Lyla who he learned, once worked with his pet Platypus agent. Good thing no one knew Ferb had known for years about Agent P.

"Hey, Ferb." Vanessa whispered as she reached the altar.
"Vanessa, you look beautiful." He said.
"Thanks, Ferb. You're not too bad yourself." She smirked and they turned to the preacher.

After the preacher had said his words, Ferb turned to Vanessa to say his vows.

"Vanessa, I promise to always try to understand you and be there for you, no matter what. I promise that even though I may be a bit younger, I'll still be the best man I can be for you because I love you." He said and slipped a ring on her left ring finger.

Vanessa tried not to tear up as she said her vows.

"Ferb, I promise to always understand your needs and wants and that I'll be there for you when you need it. Whether you grow old and sick, I'll still be there for you. I promise that even though I'm older, I'll still be the best woman for you because I love you." She promised as she slipped another ring on his left ring finger.

"Do you, Ferb Fletcher, take Vanessa Doofenshmirtz to be your lawfully wedded wife? In sickness and in health? In poverty and in wealth?" The preacher asked Ferb.
"I do." Ferb declared.
"And do you, Vanessa Doofenshmirtz, take Ferb Fletcher to be your lawfully wedded husband? In sickness and in health? In poverty and in wealth?" The preacher turned to Vanessa.
"I do." She announced with no hesitation.
"Then I pronounce you husband and wife. You may now kiss the bride." The preacher told Ferb as he smiled.

Ferb dipped Vanessa and planted a kiss on her lips, signifying their marriage.

"I love you, Vanessa Ann Doofenshmirtz Fletcher." Ferb whispered.
"I love you, Ferbs Danphil Fletcher." Vanessa whispered back.

They smiled at each other and kissed as everyone around them cheered.
