When writing this fanfiction, focus on the build - up. You can have Isabella daydreaming about Phineas, and Phineas starting to notice little things about Isabella that he never did before. For example, how she always ties her hair in a certain way when she's excited. Create a scenario where they are alone, perhaps in a treehouse they built together. The atmosphere should be just right, with a soft breeze and the smell of flowers in the air. Phineas might be telling Isabella about his latest dream, and as he looks into her eyes, he can't resist anymore and kisses her. Make sure to keep the language in line with the light - hearted and fun nature of the show.
First, understand the characters. Phineas is creative and adventurous, while Isabella is strong - willed and has a big crush on Phineas. Start with a setting, like their backyard or the school. Then, build up the tension. Maybe Isabella has been dropping hints that Phineas is oblivious to. You can add some comical moments, like Candace almost catching them in an awkward moment. As the story progresses, create a situation that makes Phineas realize his feelings for Isabella and then have him kiss her.
