I don't own Phineas and Ferb.

"What is that fantastic smell?" Phineas said as he walked out of the bathroom, after taking a shower.

"Wait, don't come in!" his wife, Isabella, exclaimed from the kitchen.

"All right," Phineas replied, intrigued. He wondered what she might have been up to; it was late in the evening after all.

"Okay, you can come in now!" she called him over after a couple of minutes.

He walked into the room and saw Isabella putting a huge baking tray, with a cake on it, on the table.

"Happy twenty-fifth birthday once again, honey," she said proudly, as she threw down her oven gloves and fell into his wide-open arms.

"Wow, Izzy... That is absolutely amazing! When did you even have the time for that?" he asked in amazement. "Thank you so much," he said finally and gave her a long, loving kiss.

"My pleasure." She smiled at him, then buried her face in his shoulder. "I had made the batter earlier, I only had to bake it. I wanted to give you one more surprise at the end of the day, so you wouldn't expect it," she explained.

"Simply incredible," he said and fell silent, hugging her tight.

After a while, she whispered, "I love you so much."

"I love you too." He cupped her face and kissed her on the forehead. They finally let go of each other.

"Thank you again, I'm... speechless." He chuckled.

"So? You wanna try it?" she asked, obviously excited to see how it came out.

"Do I?" he asked rhetorically.

They walked over to the table. Isabella started looking for a knife, but when she turned around, she saw Phineas taking a bite of the cake with a spoon right from the baking tray.

"Phineas!" she chuckled.

He smiled innocently around a mouthful of cake; a view so hilarious she couldn't help laughing.

"Ah, what the heck." She put the knife aside. "Actually, I've always wanted to eat a cake that way."

She took another spoon, Phineas grabbed the cake, and they walked out to the living room, then nestled themselves on the sofa. Somehow holding the tray on their laps, they resumed eating.

They both loved these calm and peaceful moments, when they didn't have to worry about work or other obligations, but savor what they valued most - being together. And so they were sitting on their couch, in their pajamas, cuddling and eating the cake right from the baking tray, not caring about anything at all.

Sometimes, they caught each other's eye; then, Isabella would smile and look down with her usual cute blush, and Phineas would peck her on the cheek or the temple. The quiet ticking of the clock remained unnoticed, they didn't care. The room began to get darker as the sun slowly set; so what.

Finally, Isabella rested her head on Phineas' shoulder and slowly stroked his cheek, then yawned quietly.

"On such days as birthdays," she said, her voice getting noticeably sleepy, "it always hits me how happy I am to have some people around."

He smiled, as he stroked her hair.

"But on your birthdays..." she continued. "I'm especially happy when I realise..." She yawned again. "When I realise that... I would never... That you are..." She sighed quietly.

Phineas felt her hand on his cheek fall limply to his shoulder then down his chest. She fell asleep before she was able to finish her sentence. Carefully, he put the baking tray aside and delicately lifted her up. She murmured something as he lay her on the bed and lay down next to her. She must have still been a bit conscious, as she lazily put her arm around him. He instantly hugged her back.

It occurred to him that no matter how big the parties his family threw for him, or how much fun it was to spend his birthdays with a group of his closest friends, he always loved being with Isabella the most. With her smile, her enthusiasm, her love... These were the things that made all his days, even the most ordinary ones, better.

He fell asleep holding her close, knowing there was no place he would rather be.
