A/N: So this came up after reading Welcome To The Shadowhunter Academy. I loved how Isabelle declared Simon as her boyfriend in front of whole class. That moment was priceless. But what happened after was the real inspiration for this because Simon, though I know how hard it must be for you, you shouldn't have said all those words to Isabelle.
Disclaimer: If I owned this series, Simon and Isabelle would already be together and have awesome Shadowhunter babies. But alas.
Isabelle was seething.
How dare him tell her off and apologize after! She was so mad right now she couldn't even see straight as she exited the godforsaken Academy. She felt mad and cheated and crushed. Hearing Simon awkwardly tell her he couldn't be a hero again—couldn't be that guy again, felt like someone easily shoving a hand inside her chest and plucking out her heart to feed it to the wolves. She wanted to hurt him, punch a wall and feed the bricks to him.
He had extinguished the tiny ray of hope lighting up Isabelle's darkest part of mind where everything was hopeless and dead and apologized like it was that simple. Like he didn't just turn her world upside down just after regaining its balance a few months after what had transpired in Edom. What a heartless idiot.
Magnus, who was requested both by the dean and Catarina Loss to guest lecture in the Academy, was waiting for her outside the Academy's doors, casually leaning on the wall. His cat eyes fixed gently on the girl with clenched jaws and flashing dark eyes. He felt the aura she emanated that clearly said back off or else and though he didn't feel like asking, he still did. Out of curiosity but mostly because he felt sorry for the girl. "I take it didn't go well?"
Isabelle huffed at the question and glared vehemently up at the precariously leaning tower of the Academy, cursing a certain dark-haired boy currently residing in it. "He's such a—he's such an idiot!"
Magnus knew better than to interrupt the Shadowhunter's oncoming tirade and so he kept quiet and waited for her to continue. Or perhaps, to erupt.
"He actually had the nerve to tell me he can't be Simon again. As if he changed! He just lost his memories but he can gain them back. I know he can—and it's just so infuriating that he gave up on it so easily! He… he gave up on me so easily," she finished quietly, looking down at her black boots, contemplating on using them as something to hurl at Simon's idiotic head. She didn't want to cry, especially in front of her brother's boyfriend but she could already feel the pinprick of tears slowly welling up in her eyes. She rubbed her eyes roughly before the tears could leak out.
Magnus detached himself from the wall and with his arm, softly steered Isabelle away from the Academy before she could burn it down. "Just give him some time, biscuit. You have to know that this is too much for him but I know Simon. He's going to do the best he could to regain those memories he lost from my father's fascist spell."
Isabelle took in his words quietly. She was beginning to understand Simon and the quandary he's currently in but still, did he really have to hurt her? What was he thinking, that by pushing her away she's going to pack up and immediately leave? Oh, like she would! Isabelle was a lot of things but a quitter definitely was not one of them.
"Are you going back to the Institute now?" the warlock inquired after a few moments.
She didn't know. Part of her wanted to, after all she was still mad at Simon. But a bigger part of her was telling her to stay, maybe talk to him again. She sighed, "I don't know…"
There was a knock on their rickety door.
George Lovelace leapt off his bed and opened the door to find Isabelle Lightwood out there, looking down like the floor was particularly interesting instead of something just covered in grime and dirt. "I-Isabelle Lightwood?" He couldn't help himself. He was so awestruck at this Shadowhunter in front of him, he couldn't stop his mouth from gaping. (He probably looked like a fish right now.) He knew her from the countless of stories he had heard; she had fought in the Mortal War and went into a demon realm with Simon and her friends to save the world.
Simon.
Oh, yeah. "Uh... are you perhaps looking for Simon?"
She looked up at him and saw the determination in her eyes. "Is he there?"
George nodded vigorously and called for him. Simon reluctantly got up from his bed, still depressed from the fact that he had pushed away the most amazing girl in the world, George's sure. As Simon went to tend to their guest, he collapsed again on his bed smiling slightly at the fact that Isabelle Lightwood had talked to him, if only for a few seconds.
Simon opened the door that his roommate had closed and almost faltered when he saw Isabelle outside. His heart immediately started to pound and he immediately knew he was happy, so happy, to see her again. "I-Isabelle? Wha-what are you doing here?"
Isabelle looked at him square in the eyes, "I want to talk."
"M-me too… I realized what I said a-a while ago and… and I just, just wanted to say I'm—"
"I love you."
Simon could feel his jaw drop to the floor. Did he hear her correctly? Did she just say I love you to him? He snapped his head to look at Isabelle and found her gazing evenly at him. "I-I'm… sorry?"
Isabelle squared her shoulders, not once breaking eye contact. "I love you, Simon Lewis. I love you and I choose you. You don't have to be a hero again because you already are. You may not remember what you've done but I do. And I want you to know… that I love you even if you don't remember everything at all."
It took a lot of courage for her to say that. Isabelle knew that by saying those words she was practically handing Simon her heart. Her heart that he can break into thousands of pieces in just a blink of an eye. She trusted him that much.
"But… I don't think I can ever be that guy again, Isabelle. I don't want to disappoint you further." Simon was at a loss for words. Here was a beautiful girl saying that she loves him and he didn't know what to say! He came here to the Academy to get away from them because he couldn't stand seeing the disappointment in their eyes whenever he came up blank and now Isabelle was here brazenly declaring her feelings out in the open—again.
Isabelle finally looked away. "I just want you to remember me, Simon. That's all I ever want."
Simon's heart went out to her. He found himself tugging at her arm and slowly enveloping her in a hug. For a fleeting moment, she looked like she wanted to pull away but the look was gone immediately as it came and she surged forward, clasping her hands behind his back.
"I just want you to not forget me," she whispered, her voice softly cracking under the weight of emotions she was drowning in.
He nodded, momentarily distracted at the familiarity of her in his arms. He was assaulted by her scent, a sweet yet soothing vanilla, and he realized how much he loved that smell. How much he missed it. "I-Isabelle, I'm going to try. I'm going to be a Shadowhunter and Ascend and get those memories back. I don't want to see you sad anymore. I don't want to hurt you by disappointing you. But I just—I won't be that guy again, you have to know that. We're going to change and I-I just hope that you're still going to… want me, after that. Because my mind may not know this but my heart… it remembers. And it remembers that I love you, Isabelle Lightwood. I do."
Simon didn't know where the courage to say that came from but he had a feeling that it was because of the girl tightly clutching him at the moment. He relished in the warmth and feeling that was Isabelle Lightwood and he was mad at himself for displaying such stupidity just a few hours ago at her. It wasn't an awesome moment for either of them.
Isabelle could feel her heart beating so hard in her chest but she found that she didn't care. Listening to Simon's words felt like flying. She buried her face in the crook of his neck and breathed in his smell redolent of warm summers and coffee. "I'm still going to want you, Simon. You're... you're all I ever wanted."
"Wait for me for two years?"
She smiled. "I'll wait for you forever."
A/N: Too cheesy, I know. But I hope you enjoyed reading this as much I had fun writing it. My Sizzy heart is slightly better now! And oh, by the way, please know that the stories are unrelated to one another. They happen between Simon's life as a Daylighter, as an amnesiac mundane and (hopefully) as a Shadowhunter. I'm always open to prompts and requests so if you have something, just throw them my way!
