A/N: Hey! Thanks so much for the reviews to Exotos135, EnergeticBullet, LittleMsZodiac, VanessaCorduroy, Rorscarch and Gigglebox15!
Again, sorry for the lack of frequent updates (my life has been sucked by other fandoms, please understand :P), and because of that, I really hope you enjoy the new chapter.
I don't own Phineas and Ferb.

Isabella closed her textbook, as she straightened up in her seat.

"So," she said briskly, "I think I gotta go home. We've been studying for a long time."

"You're going already? You sure we talked over everything?" asked Phineas. "You came like..." He glanced at his wristwatch. "Oh. Four hours ago," he realised with surprise.

"Yeah," she admitted sheepishly. "Sorry for taking so much of your time, guys."

"You know that's no problem," assured Phineas, and Ferb nodded in agreement.

"Thanks." Isabella smiled. "Anyway," she said as she stood up and started gathering her stuff that was scattered across the desk, "I really have to go."

"All right. I'll walk you to the door," offered Phineas.

"Cool," Isabella stated cheerfully. "Oh, wait, where's my phone?" She dug through her bag.

"Maybe it's on the desk?" offered Phineas, looking around.

Isabella kept feeling around in her bag. "No, I'm sure I just threw it here, this bag is just... bottomless," she uttered as she struggled to find her phone.

"I can call you," suggested Phineas.

"Oh. Okay, that's a gre-" Isabella stopped as she remembered something. The song she set as his ringtone. He can't know. No. Way.

"No no no no you don't have to!" she burst out in protests. "Or... Ferb can call! I don't wanna... uh... I mean... Ferb is already holding his mobile, so... don't worry about it." She laughed nervously.

She sent Ferb a very meaningful look, seeming almost like a threat, hoping he would understand. After a couple of seconds of silence, during which Isabella was silently persuading Ferb, and Phineas was trying to understand what on Earth was going on, Ferb finally grasped the reason of his friend's behaviour.

"Of course," he said calmly, and Isabella let out an unnoticeable sigh of relief. Seconds later, her phone started buzzing and ringing somewhere in the bag.

"Okay, it's there, that's all I needed to know," she said jauntily, as if she hadn't looked like she had wanted to kill Ferb just a moment ago.

"Uh, what was... what was that really about, guys?" Phineas asked, obviously confused.

"Ah, ya know," she said playfully, trying to save the situation (and utterly failing), "just... things and... other stupid stuff." She laughed a bit too loudly.

Phineas seemed dumbfounded at Isabella's reply, but decided to roll with it.

"Well, you can't argue with that!" He shrugged, chuckling, but raised an eyebrow as she turned around.

"I know, right?" she asked, wondering if the relief in her voice was too obvious and if she had discredited herself completely yet. She zipped her bag.

"So? Shall we go downstairs?"

"Sure," replied Phineas.

"Bye, Ferb! Thanks!" exclaimed Isabella from the hall, to which he raised his thumb in reply.

Ferb sat silent for a moment, while Phineas and Isabella's muffled yet lively chatting came from downstairs. Hadn't they both noticed each other's behaviour minutes ago? He smirked to himself.

Love is not blind. It just makes one blind.

Thanks for reading and please review!
ElleFreak is out, peace!
