A/N: Characters are around 16/17. The idea came from kjasdhflasgfklhas. I am sorry it took me so long to get this story written and published, but I hope you still enjoy. I decided to do two parts for this. Part 1 will be in Ferb's POV, while Part 2 will be in Isabella's POV. I hope I have given justice to the idea.

Prompt: Ferb and Isabella go to see a hypnotist show, and Isabella gets hypnotized in the audience by mistake. She's given a post-hypnotic suggestion that for the rest of the night, anytime she hears a bell ring, she'll have an increasing urge to kiss the boy she likes. So, the entire day, she's trying to resist the compulsion, but it gets stronger and stronger every time she hears a bell until eventually, she can't stop herself. Ferb, of course, thinks that will be Phineas. But Isabella, who's desperately trying to fight the compulsion, eventually does end up kissing Ferb. (As a side bonus for comedy, she's also given a 2nd post-hypnotic suggestion that anytime she hears someone snap their fingers, she'll uncontrollably start clucking like a chicken until she hears someone snap again).


Ferb POV

Since this morning, Isabella has been acting strange. She wasn't necessarily avoiding us, because she was here, helping us decide what to build. Although she is just rejecting all of Phineas' ideas – harmless ideas (at least I thought so) – but Isabella had a continuous panicked look. I really don't know why she is rejecting idea after idea especially since they were all different. The one thing that was a common factor in all plans were bells. Oh... OH... Earlier this morning, Isabella and I went to a hypnotist show. She was never called on stage, but maybe she was still affected.

Flashback (3rd person POV)

"Do I have a volunteer for my next hypnosis? Hmm, how about you young lady?" The hypnotist pointed at a blonde girl sitting a few rows behind Ferb and Isabella. They came to the show as they were curious about hypnosis, but Phineas had absolutely no interest in the subject.

The blonde girl shyly went up on the small stage and sat on the chair. They hypnotist asked her to pay close attention to his words. When he was sure she was "under", he gave her the suggestion: "Until midnight, the urge to kiss the boy you truly love will increase with every ringing bell that you hear."

Ferb thought that suggestion would have been perfect for Isabella as this might have finally helped her with Phineas. The hypnotist released the girl and rang a bell, and at that moment, Ferb noticed in the corner of his eyes that Isabella jolted, but he thought nothing of it.

Present (Ferb POV)

If Isabella got accidentally hypnotized and gets a growing urge to kiss the boy she loves, then whatever we build today will help her.

"I have liked every idea so far. Which would mean that it is two in favor for these inventions and one against. Bella, if you agree to one of these inventions for today, then tomorrow we will do whatever you want."

Phineas started beaming and nodding enthusiastically, whereas Isabella was looking worried, but eventually she agreed. Phineas jumped up from his seat under the tree and exclaimed "I know what we're going to do today!" He snapped his fingers and ran inside. As I turned to Isabella to make sure she was alright, I noticed that she was very rigid and staring straight ahead into nothingness.

"Bella...?"

Her head snapped in my direction and when she opened her mouth to respond, she started clucking like a chicken. I started laughing so hard, I was getting tears in my eyes. Isabella got more than the one suggestion this morning as it would seem. Isabella couldn't stop clucking and I couldn't stop laughing. Phineas came back out and was completely shocked. He gave me a questioning look to explain what was happening. I needed to take several deep breaths before I could answer him.

"I believe Isabella was hypnotized during the show this morning, where she uncontrollably clucks like a chicken when someone snaps their fingers. To stop her, one must snap their fingers again."

Phineas tried keeping a straight face at first, but quickly started laughing as well. Isabella continued clucking looking between Phineas and me. Phineas and I laughed a bit longer.

"Perhaps we should release her." I snap my fingers and Isabella stops clucking. She shakes her head and stares at us. Phineas and I were still chuckling a bit. I was shaking my head in amusement as she shoots me a look asking what happened. I can't help but cluck like a chicken. Her reaction is priceless. Phineas laughs louder and Isabella's eyes grow wide as she looks petrified. I felt slightly bad for her, but I would make up for it. She is getting her chance with Phineas.

"Alright guys, let's get started." Phineas lays out his blueprints and began explaining the idea to us – a puzzling high rise, where each floor would be a new puzzle, and the difficulty would increase the higher we would go in the building. It did seem like fun, especially as with every puzzle we solved, a bell would ring. Isabella seemed rigid again hearing the bell part. I could tell she was afraid of what could happen, but all the failed attempts with Phineas weren't doing her any favors. This was the only way I could help her. I gave my brother a big smile and a thumbs up. When he didn't look, I gave Isabella a pointed look, which seemed to do the trick, and with that we started working.

*time skip a few hours*

It wasn't easy, but we finally finished. Every time I thought we had enough levels, Phineas wanted more. At least Isabella would have her chance of kissing Phineas and without a way to chicken out. That's what matter to me. Even if it hurt. Isabella is easily my best friend (and no Phineas doesn't count as he is my brother), but I did the one thing I shouldn't have done – I fell in love with her. From the moment I met her, I found her fascinating. Over the years, that fascination turned into admiration and infatuation. I would have told her long ago, but she's always been in love with Phineas and if he is the one that will make her happy, then I will remain the supportive best friend. I just want her to be happy.

As Phineas goes to the garage to return the tools, I quickly turn to Isabella and see that she is completely scared. I take her hands and caress her knuckles with my thumbs, whispering to her "Breathe darling." She closes her eyes and takes a deep breath. I hear Phineas returning, so I regretfully drop Isabella's hands, take a deep breathe myself, and take some steps away from her.

"You guys ready? Remember we have a maximum of 15 minutes to complete each level. When we defeat a level, a bell will ring, and when we have a minute remaining, it will be a buzzer. If we don't pass a level, we start from the beginning. To get out, we have to solve all levels. Any questions?"

We shake our heads and the three of us head into the building. As we wanted to increase difficulty going up, we made the first few levels very easy. This would also allow us to get the hang of it and there would be lots of bells in Isabella's future. Within two minutes, we solved the first level and the bells rings. I keep an eye on Isabella and see how she closes her eyes and bites her lip, almost as if to keep a moan quiet. Well... crap... that is a hot thought. NO FERB! PHINEAS! SHE LIKES PHINEAS! I breathe deeply and keep walking behind Isabella and Phineas.

We enter the next puzzle and although the difficulty increased slightly, we still manage to get through the puzzle quickly. Isabella is right next to me this time and can't hide it fast enough this time around. A quiet (but still audible to me) gasp and moan escape from her. My God. This girl might kill me with these reactions, as long as she tries to hold off on her urges. I gently nudge her forwards toward Phineas and walk behind them, taking some deep breaths to control my own urges.

This continues for another couple of levels. Isabella is struggling to keep control and I know a few more bells and she will pounce on Phineas. Yet she's never near him when the bell rings, she keeps close to me. I need her to be near him, otherwise this is going to be awkward for me.

Luckily the next level requires Phineas and Isabella to work closely together, which means I can keep to myself far away and let them have their moment. I just hope this works out otherwise the rest of these levels are going to be very awkward. At least I put an escape hatch every 25 levels, so as long as we get to level 25, we will be fine.

I walk away from Phineas and Isabella as they work on solving the current puzzle and find a nice wall I can chill behind. They have their privacy, and I don't have to watch and feel my heart break.

Soon I hear the bell ring, along with a groan.

"Isabella, are you ok?" No Phineas, she wants to kiss you and won't give in to her stupid urges. "I'm alright Phineas. I just… I need Ferb. Where is he?" Me? Why does she need me? She just needs to kiss Phineas. Back to helping her and motivating to just go for it. I come out from behind the wall, seeing both of them looking for me.

"There you are Ferb. I'll head up to the next level. You two can follow." As Phineas walks past me, he whispers to me "Just do what you need to do. And don't hesitate on my account." I look confused as he walks away. What did he mean don't hesitate? I would never hesitate to help Isabella.

"Bella, what's wrong?" I walk a bit closer to her, until we still have space but are much closer. "You have no way to chicken out from kissing Phineas. I know the suggestion from the hypnotist affected you. You hear a bell, and you have a growing urge to kiss the boy you love – Phineas." Isabella looks to the floor, but I can still see her face growing pink. The blush grows all the way to the tips of her ears and it's the cutest blush I have ever seen.

"Ferb… the urge is growing but it's not for Phineas." I am more confused than before. "Not Phineas?" She shakes her slightly, just enough to answer my question, but my confusion remains. If it's not Phineas, then who? I try to remember exactly what the hypnotist said to the other girl during the show. Until midnight, the urge to kiss the boy you truly love will increase with every ringing bell that you hear. The boy you truly love… and it's not Phineas… but she's loved him since were small kids, roughly 10 years that she's been crushing on him. And he's not the boy she truly loves?!

"Bella, that doesn't make sense. You have loved Phineas for 10 years. How is he not the boy you truly love?" I turn away from her and run my hands through my hair. This is not good. I tried helping her and now it's backfiring. Whoever this other guy is would probably get the biggest kiss from Isabella if we got her out of here. But I could have never predicted what came next. Isabella answers so quietly I barely hear her answer.

"Ferb, if you call me Bella one more time, it will be worse than a ringing bell."

"Well, another bell will likely ring soon if Phineas can solve the next puzzle on his own. Just… just tell me who it is, and we will get you out of here. I put in escape hatches every 25 levels. I just wanted to give you the chance to get out if things went downhill."

"You did?"

"Of course, I did. I care about you and just want what's best for you."

"Is that why you call me Bella instead of Izzy like everyone else? Because you care about me? Is that why you called me darling before we started these puzzles? Caressing my knuckles when I am going to panic, and you know physical touch is the one thing that calms me? All that because you care?"

Looks like I might have been more obvious than I thought.

"Yes Bella. I care. Which means you need to tell me who the boy is before more bells start ringing and we can find a way to keep you controlled until we get you out of here."

I barely finish the sentence as we hear a bell go off again. And my god – Isabella has got it bad. She bites her lip, closes her eyes, moans loudly, and leans forward, almost falling to the ground. I was luckily fast enough to wrap my hands around her upper arms and steady her. She seems almost in a daze.

"B-Bella? Darling, are you ok?"

"Ferb… Kiss me."

Don't hesitate on my account. Oh Phineas, thank you. I take another two seconds but see the want in her eyes and swoop forward. Isabella throws her arms around my neck and leans into me. My arms snake around her waist and pull her in more. She moans and my god, she is doing that for me… because of me… I don't even know. It feels incredible to have her in my arms, kissing her, loving her. She swipes her tongue across my lip begging for entrance, which I happily grant her. We battle for dominance with me winning. I explore her mouth and get her to moan some more… and louder. We break away once air becomes a necessity. We are both breathing heavily, trying to catch our breath. As incredible as that kiss was, I need to know the truth.

"Bella, darling, was the urge for me? Or…?" I couldn't quite finish the heartbreaking thought.

"The urge was for you Ferb. It was never Phineas. I mean yes when we were kids, it was so easy to have a crush on Phineas and because everyone knew, it was easy to continue a charade. But I fell in love with my best friend instead – you. I could never bring myself to tell you. I didn't want to lose you."

She loves me? I stay quiet as I see her having more on her mind that she needs to get out. But she loves me! I smile a little as she continues rambling. My hands remain on her waist, hers on my chest.

"I don't think any of what just happened would have happened without the hypnotist and his suggestion. After the show I heard the first bell and immediately knew I got affected. When Phineas was bringing up all the suggestions with bells, I knew I was doomed. I didn't want to jump you in front of Phineas and then have to explain myself to both of you. So, I told Phineas that I needed some alone time with you because I had to talk to you privately. Phineas agreed immediately, which makes me think he knows that I love you."

He probably figured it out. He isn't that oblivious.

"But with every level, the urge kept growing, especially because with all three of us being smart, specifically the two of you, I knew bells would ring every couple of minutes. And Ferb, we have listened to 14 bells, or at least that's what it feels like. As amazing as that kiss was, because trust me, it was amazing and life changing and perfect – the urge is still there, almost a hunger if I am honest, a hunger for you. But Ferb if you would rather, we stay friends, then I will certainly understand. If you kissed me because you felt bad for me, thank you for always being my knight in shining armor. But I just need to know."

She looks up at me with glassy eyes. I can't help but admire her. My hand leaves her waist and cradles her cheek, as my thumb traces circles. I have always been a man of action, although my darling Isabella is one of two people who can make me talk for a long time. I rush forward and capture Isabella's lips again. She sighs against my lips, and I can't help but smile. Making kissing her more difficult, but not impossible. She leans back slightly, keeping her eyes closed, while I keep my eyes on her.

"Ferb, I know you are actions over words, but I need you to use words this time otherwise I might not believe it."

"You are incredible my darling. I love you. I have since I met you."

Her eyes spring open and widen as she looks at me. I smile lovingly at her and continue caressing her cheek.

"I don't want to be friends anymore. I can't be friends with you. Not when I am so hopelessly in love with you."

This time Isabella initiates the kiss. She jumps into my arms and we both moan and groan into the kiss. With her jump, I had to make sure she stays balanced in my arms, her feet are barely on the ground because of our height difference. Regardless, we put all our emotions into this kiss. She breaks away from the kiss just enough to speak, but close enough that our noses touch.

"How long until we can get out of here and just be by ourselves to continue this? Because my urge is still there."

I chuckle and peck her once more on the lips.

"We have to reach level 25, then we have an escape hatch. And with Phineas knowing about our respective feelings, I don't think he will mind if I kiss you for every bell. To somewhat contain your urge until we are out. How does that sound my love?"

"Mmm ok if you say so." She gives me a peck. "Wait, love? New nickname?"

I laugh loudly this time. "Yes, a new nickname. And one last question before we catch up to Phineas." I get down on my knees, grabbing her hands. Her eyes grow wide once more.

"Relax my love. I am not proposing… yet. My darling Bella, I've fallen deeply in love with you. Your smile, your presence, everything about you fills my heart with joy. I can't imagine my life without you. Would you do me the incredible honor of being my girlfriend?"

She gets tears in her eyes and the biggest smile possible on her face. She enthusiastically nods her head and whispers the one word I wanted to hear more than anything else: "yes".

I wrap my arms around her waist as I get up, lift her in the air, and spin her around. She is laughing, which is music to my ears. I gently put her down and kiss her once more.

"Let's go catch up and get out of here. I owe you a proper date. And a big thank you to the hypnotist."

We rush to catch up to Phineas. He sees our joint hands and smiles brightly. "Did you two finally figure it out? That took way too long but I am happy for you guys. I'm assuming you planned an escape hatch somewhere in the puzzle, right Ferb? Which level?"

I grin and say "25". I pull Isabella into my side and kiss the top of her head. I look back to my brother, who has the biggest (and happiest) grin on his face. "There is one more thing Phineas. Isabella didn't just get the suggestion to cluck like a chicken, but she got another suggestion where bells affect her. Until we reach level 25, I have to kiss my darling girlfriend every time a bell rings."

Phineas laughs loudly and Isabella hides her face in my chest. It feels so good to have her in my arms, protecting her, making her feel safe and loved. "Alright then let's get you guys out of here so you can enjoy your first date, which I am assuming will be happening tonight. Because if you didn't ask her on a date already, I will come after you Ferb."

"Yes, we are going on a date tonight, something without bells."

Phineas and I keep laughing, while Isabella blushes. By this point, Phineas has just finished solving level 17, which means the bell goes off. I quickly kiss Isabella, leaving her breathless. I push her slightly to get her moving again. This repeats up to level 25. I quickly show them where I made the escape hatch, and a slide extends. We all slide down and once we are out, I push a button which folds the high rise into a cube that we can store (and use later if we wanted to finish it).

Phineas went inside, while I turned to Isabella, who immediately kissed me. I groaned into the kiss, pulling her closer to me by her waist. All too reluctantly, I pulled away from the kiss.

"My darling Bella, I will come and pick you up at 7 for our date. Fancy restaurant, so you can get dressed up. I will drive. You go home and get ready, and I will see you in a little bit. I promise no more bells, at least not on purpose."

She grinned up at me and gave me one last kiss before heading home. I stared after her. My girlfriend. My love. My Bella.
