"Raphael!" Her voice echoed through the intense Institute hallways.

Raphael paused. He didn't need her to yell his name to catch his attention, he could smell the familiar sweet scent of her pumping shadowhunter blood from a mile away.

As Isabelle got closer, her sound of her steps faltered. His back was still on her and suddenly the pace of her heart fastened. Isabelle is usually a smooth talker but she hesitated before saying her purpose. But she had to get it out.

Slowly, Raphael turned around. His hair was still sitting stiff in it's usual place, poker face a little softened, handsome face still there, Isabelle didn't know what it was about him today that seemed... extra.

Isabelle got rid of her thoughts in a millisecond. They stood face to face.

"Isabelle." His dark voice softly said.

Isabelle exhaled the air her in her lungs and looked at him dead straight in the eyes.

"Raphael." She started, she quickly got rid of the lump in her throat, "I know what we feel for each other and... it's real."

Raphael furrowed his brows in confusion and changed his stance, unaware of Isabelle sudden confession.

"I... I know what we have and... I'm going to fight for it."

And at that moment, Raphael swore he felt his heart beat again for the first time in a very long time.

-line break-

It was probably 3 am and the party was long over. Raphael secretly smiled to himself. How can they be so reckless? As far as he's concerned, the institute believes all of the downworlders went home, that they're home is downworlder free. How easy was it for a vampire to spend the night in the institute.

Here he was, lying on Isabelle Lightwood's bed, polo shirt unbuttoned all the way as he cradled her gentle naked body. Raphael knew he can't rest and keep his guard down. Sneaking into the institute like this is a serious crime.

The institute was opened 24/7, with his sharp hearing he could still hear their soft chatters down stairs.

He continued stroking Isabelle's warm arm. It was almost like a joke, dating a shadowhunter- and even more, sleeping with them. He was never the type to encourage sex, but Isabelle made it work.

He smiled secretly again in the dark, funny how someone who's technically dead can have so much feelings. Feelings he ever thought he would experience. He never really had a chance back when he was alive.

Isabelle had been sleeping for 2 hours now and Raphael thought of all of the possibilities this relationship can end badly. He tried not to be a pessimist, really. As Isabelle is aging, he isn't. He shook his head, 'That's everyone's problem,' he thought. Not long ago, Raphael would chuckle to himself thinking about Alec and Magnus and Simon and Clary. 'Fools' he would think to himself. Correction: 'Fools in love'. Like he was now.

Everything he's thought about tonight, he definitely won't share with no one else, thoughts were too sappy, even for him.

"Mmm..." Isabelle moved closer to him and buried her face on his neck, also wrapping her long legs around his waist. She was small compared to him. He held her tighter and he wondered, she shouldn't be this comfortable if she's hugging a cold piece of wood.

"Mmm..." She muttered again, nuzzling his neck closer. He pulled the covers up to cover her more, she was cold, he could tell by the two little nubs poking his chest.

Her eyes fluttered open. She smiled. He was still here. Without a word, she softly straddled him, leaving the covers gathering around her hips, crushing his lips against hers.

In 30 seconds, things got pretty heated, seeing as they proceeded with their well paced rocking. Raphael was biting her shoulder, not enough to make it bleed. He wouldn't want to ruin her recovery.

Isabelle has never been so glad she replaced her creaky bed last year.

Suddenly, the door bursts open. There stood Alec.

"Alec!" Isabelle gasped as she gathered the covers around her. Raphael was frozen from his spot, there was no way he could out run this.

Alec's face changed so quick, Isabelle knew she had to untangle her self from Raphael.

Alec growled, "What do you think you're doing?" He went for Raphael.

Luckily, Isabelle was fast, still maintaining her covers around her body and Raphael's lower body, she held her hand on Alec's chest.

"Alec, stop!" She said firmly and trying to control her voice.

"Really Izzy? In here? I thought you were over him,"

Raphael just waited patiently as Alec was shooting daggers at him with his eyes.

"Well, it's different now. I'm willing to fight for him." She tried to explain, "Someone told me I should fight for love, and I am!"

"With a vampire?"

Raphael's eyebrows rose.

Isabelle reduced the pressure she had on Alec, "You of all people should know."

Alec hesitated, "That's completely different."

"How?"

"You're endangering-"

"Endangering what?"

Raphael finally stood up, he eventually managed to pull his pants up under the covers.

Isabelle looked at him. "I should be going," He said to Isabelle.

"N-"

"Izzy." Alec stared down Raphael with deadly glares.

"No, Alec! If he's going, I'm going!"

"Izzy, we don't want anyone knowing about this," Alec tried to reason with her.

"Isabelle, it's fine. I'll see you very soon." With that Raphael was gone.

Isabelle's mood dropped so suddenly.

"Izzy-"

"No, Alec! Get out!"
