Okay so this is my 4th fanfic. More WillxTessa fluffiness!

Will's POV

It was midnight in the Institute, and like always, Will Herondale was wondering the corridors. He was no longer able to rummage for sweets in the kitchen since Agatha was gone, nor could he visit the library for fear of running into Tessa, so he wondered the halls. Will never had any particular destination, but his roaming gave his body something to do while his mind was at work.

He thought a lot. About Jem's declining health, about Charlotte's frail grip in the enclave, but mostly how he wished he could take back what he'd said to Tessa on the roof two days ago. It was a mistake and as soon as he saw her face crumple in response it was hard to stop an apology from spilling out of his mouth.

Avoiding her was torture. Not seeing her beautiful face, or hear her witty remarks had taken their toll on him. He knew though, that it was best for her to not see him. He had to do something nice to counteract the mean things he had said, even if she didn't notice.

Tonight, his wanderings had taken him down to Jem's room to check in. He opened the door to find Jem strewn across the bed in what looked like a very uncomfortable position, his blankets in a pile on the floor. It took him nearly five minutes to right Jem into something that resembled a normal sleeping position and lay the blankets back on top of him. Jem must have been really completely asleep to not wake through any of that Will thought. Satisfied with his good deed for the night, he left the room to wonder again, no destination in mind.

Will stopped after he closed the door. He could hear a muffled sound coming from across the hall. He looked over and saw that the door to Tessa's room was open a crack. He heard it again, though this time he could discern that it was a sob being muffled by pillows. He walked over noiselessly to the door and peaked in. What he saw took his breath away both from sheer beauty and overwhelming sadness.

Tessa lay on her side curled in a ball with her back to him, her body racked with stifled sobs. Her brown hair lay in tangles down her back and along her side, her white nightgown shimmered in the moonlight that streamed in from the window. He just watched for a minute before opening the door a little more to slip in.

"Tess," immediately alerted to another person's presence in the room she sat up and looked at him. Her eyes were red and puffy, but even then she looked beautiful to Will. "Tess, I heard you crying. Are you okay?" She looked at him with a look of pain that hurt him to look at.

"Leave Will, just leave." Then she turned away and began to cry again. He turned to go, opening the door and closing it after he left, staring at the wood. He listened to her cry for two minutes then burst open the door. She spun to look at him again.

"I told you to go Will. I don't want you here." She looked him square in the eye and that was all it took for him to know she was lying. He sat next to her on the bed and pulled her into him and held her. She made no move to pull away, only sobbed harder.

She grabbed a fistful of his shirt and buried her head in his chest as he held her and rubbed circles into her back with his thumb. He put his face into her hair and inhaled the scent of her, light lavender.

They sat there for a while, him holding her, her crying into his chest till the tears slowed and her breathing evened out. Her grip on his shirt loosened and she began to slump a little in his arms. She was holding him to her so he had no choice but to lay down there with her attached, where he fell asleep.

Will awoke, slightly confused as to where he was, and felt an unfamiliar lightness in his chest. He sat up and realized he was in Tessa's bed, but there was no Tessa. He sat up and looked around, finding her night clothes in a chair. Groggily, he got up to go search for her.

Tessa's POV

Tessa sat in the library a book in hand, though she paid it no thought. She was so embarrassed, just the thought of last night brought the blood rushing to her cheeks. She should have been more adamant in pushing Will away. She did not want him to see her cry. Now she would have to face him about it. Eventually, but not now she decided as she went to go find a better hiding spot

As Tessa wondered the corridor, she heard footsteps coming from the direction of her room. Assuming it was Will, she ducted behind a curtain just in time to see Jem's silver hair as he rounded the corner. Feeling silly, she stayed in her hiding spot and watched him continue on. She stepped from her hiding place, looked over her shoulder to check if Jem had seen, and walked right into something, no, someone tall and muscular.

Dreading what she might see, she looked right up into the midnight blue eyes. Silently she cursed her bad luck as she heard Will chuckle. His hair was disheveled from sleep, and he was wearing the same clothes as last night, but he still looked gorgeous.

"Tessa, what were you doing in the curtains." He looked at her with a glint of amusement. She instantly regretted hiding there.

"If you'll excuse me Mr. Herondale, I really must be going. I have something important to attend to." She was lying through her teeth, though he didn't have to know that.

"What could be more important than me? I feel quite offended. Comfort me?" He was mocking her. She wound up to hit him but he saw and caught her wrist before it hit his face. He began to tow her down the corridor, though where, she wasn't quite sure. She dug her heels into the floor, but she wasn't wearing any shoes so she just slid.

"Mr. Herondale, where are you taking me!" She exclaimed as they rounded yet another corridor.

"Aren't we past formalities Tess?" She tried to ignore the shot of heat the nickname gave her. He opened a door on their right and lead her in. It appeared to be another of the Institute's bedrooms, except that it had been converted into somewhat of a second library. There were more bookshelves than even Tessa's room and all were filled with books.

"Now since I'm assuming you were hiding from me in that curtain, I'm not giving you a place to hide. You're not leaving until you explain why you were crying last night." He looked at her with a serious face, all traces of humor gone. She bit her lip. Seeing no other option, she gave him an answer.

"My broth-Nathaniel." She couldn't associate with him anymore. He was dead to her. Will eyed her with something like suspicion.

"I can tell that's not the only reason Tess." He said it so softly she almost missed it. She contemplated whether to say the other reason. He walked over to the bed and flopped down. She decided to avoid his question.

"What is this room?" She was honestly curious. It seemed like something someone had made, not just found.

"This is my hideaway. I made it back when I first moved to the Institute. The library seemed to public so I made my own library to come and think. You're avoiding my question," he observed. She took a moment, then bolted for the door. With speed only a Shadowhunter could accomplish, he had her pinned against the wall next to the door.

"Tessa," His voice came out softly, his breath in warm puffs, "why are you so upset?" He caressed her cheek gently. She didn't want to cry in front of him again, but she could feel the knot in the back of her throat.

"Tell me you honestly don't know." She tilted her head down, but his thumb slipped under her chin and tilted it back up. She looked at him and saw a kind of pain hidden in his eyes.

"I'm sorry." He looked like he honestly meant it, but Tessa wasn't falling for it so easily.

"Please Will, just let me go." She tried to speak evenly, but her voice cracked on 'me'. He looked at her with what could have been confliction, but leaned in and put his mouth to hers gently.

She stood there for a minute, his lips pressed to hers, unmoving. Then all at once, his hands circled her waist and hers wrapped around his neck and the kiss spread like wildfire throughout her system. The feel of his mouth on hers was like nothing she'd ever felt before. His hands moved to her hair, and her clip fell to the floor. She realized they were alone in a bedroom and pulled away.

Will seemed a little dazed, and they were both breathless, so Tessa took the opportunity to slip from his grip and slide out the door before he could do anything. She ran around the corner and up the stairs to the attic.

She barely made it before the tears started again. Will was playing with her. No matter that she was a broken toy now, he just liked to watch her squirm. She was done with it.

She hid up in the attic for who knew how long. After dinner, Sophie came up and found her asleep on the ground. She called Charlotte and Henry who carried Tessa back to her bed where she slept away her misery.

Well? I'm probably gonna take a hiatus because I'm working on something of my own, but I guess if like 30 people really want me to continue this, or make another one, I'll throw something together. Until then! Remember to review!
