"Surprise!"

Making sure her act was perfect, Blair widened her eyes in disbelief and smiled. "I can't believe it!"

After all the welcoming and hugging had been finished, Chuck approached Blair and whispered. "Please, Blair, I can see through your little façade." He smirked at Blair's astounded expression, "You totally knew about the party, your excitement was a little overdone. Next time, try not to widen the eyes so much."

Blair sighed in relief as Chuck walked off smugly. She laughed shakily to herself, seeing him feeling omniscient, when in reality he didn't know a thing. The note, Blair checked, was still in the side pocket of her purse. She knew that it was perilous to play with fire, and Chuck was an inferno. The sensible side of her brain claimed that she was doing this for closure. But the way her heart beat fast in her chest told her she was desperate to feel his lips on hers again. Blair blamed it on lust, knowing that she would never admit to herself that she, Blair Waldorf, had any type of affection for Chuck Bass.

She would wait until Chuck had downed a few glasses of wine, so that he wouldn't be able to know who the note was really from. Blair liked to think that Chuck knew her handwriting. She knew she wouldn't have to wait long. Chuck Bass was one to get tipsy soon after the party begun. He always liked to be ahead of things.

…

Blair eyed Chuck carefully, evaluating his level of intoxication. She figured it was safe to begin her plan. Nonchalantly, Blair edged closer towards Chuck, squeezing herself carefully in between a dancing couple. Once Blair's heart was speeding up and she could feel the soft silk of his scarf, she guessed that she was close enough. Slowly, yet quickly, she slipped the tiny note into the front pocket of his pants. If Chuck were sober, he would have noticed. But since he was not, he continued bopping his head to the music, completely oblivious to the fact that his princess had snuck off to an empty room to ready herself for him.

…

It was ten minutes later when Chuck found the note.

Rooftop. 9:00 p.m. don't be late. Your princess awaits her Dark Knight. She doesn't like to be kept waiting.

He couldn't help but scoff at the banality of the last sentence, but it just made him admire her more. He quickly checked his phone, and realized that there were only five minutes left. Don't be late. He imagined the way she would say it. The sound of her voice rang in his ears. Needless to say, anyone who got in the way of him and that rooftop would find themselves in jeopardy.

…

He got there at 9:02. Stairs were not an easy task for an intoxicated man.

"You're late." She wore nothing more than a nude slip and her silver mask.

"My apologies." He was trying hard not to suffocate right there on the spot. "How did you know it was me?"

"One of us had to discover the other's identity. And I'd rather you had not been the first to do so."

"I see." Chuck grinned. He adored her when she spoke in that posh manner.

"So are you just going to stand there like a giddy idiot?" A smile played on her lips. "Or are you going to kiss me?"

His lips were on hers as she barely finished the sentence. Any place their skin met brought fire. It was as if the rooftop was ablaze, and it felt good. Her body pressed straight up against his yet he still pulled her closer to him.

"I thought you didn't want me anymore." Chuck murmured onto her tongue.

"I lied." She bit his lip softly.

"Why?"

"I thought it'd be better that way."

"Then why did you invite me up here tonight?"

"It was inevitable."

He liked the way her words flitted across the air, elongating the moment. Slowly, but surely, Chuck reached a hand over to her shoulder and gently pulled on the strap of her slip.

"What do you think you're doing?" She bit down on his lip hard this time, and the pain was insanely pleasurable.

"I think you know." His snarl was heavy with lust.

"You don't even know who I am." Goose bumps rose where her lips touched his skin.

"I'll find out soon."

"No you won't."

"Are you sure?"

The way she kissed him now meant that she could care less. And he was perfectly at ease with that.

…

Back down at the party, many began noticing that the person the party was specifically thrown for was missing. Quiet and confused murmurs ran through the guests.

"I'll check my room." Serena smiled. "Maybe she's in there."

She walked up the stairs, glancing at the guests, noting that Chuck was also missing from the crowd.

"Blair?" Serena called, hitting the light switch. Blair wasn't there, but a carefully printed note lay on her bed.

Mother called. Have to leave immediately. Sorry. –B

Serena laughed, because though her best friend had an exceptional talent for lying, this was just way too obvious.

…

Chuck lay panting on the rooftop floor facing the night sky. Blair was inches away, her mask perfectly intact, despite recent events. Chuck noticed that his hand was barely touching hers. He wanted so badly to reach out and grab it, but intimidation got the best of him. The moment was so perfect, and he didn't want to ruin it by touching her hand, possibly causing her to pull away.

"Everything okay?" Blair glanced nervously at Chuck. He was strangely quiet, and Blair was worried that she had done something wrong. This was, after all, her first time, and probably his fiftieth.

"Everything's fine." Chuck murmured contently. He turned and leaned on his side to face her. "Tell me about yourself."

Blair inadvertently reached up to touch her mask, the only thing that protected her identity from Chuck. "What do you want to know?"

"How old are you?"

"Same age as you."

"I'm guessing you know who I am?"

Blair nodded tentatively, fearing that she'd give away more than she intended.

"Do I know who you are?" Chuck pressed.

Blair's lips twitched. "Maybe."

Chuck groaned impatiently. "You have to give me something to work off of."

"That would indicate that I want to be found out."

"And do you?"

Blair frowned. "I don't know."

Chuck smiled, satisfied that he had trapped her in a dilemma. "Well…do you expect us to go on like this without me knowing who you are?"

Blair stared shockingly at Chuck. "I wasn't aware that there was an 'us'."

Chuck bit his lip. Had he just said the wrong thing? Had he freaked her out? "I…"

Blair watched intently as he stammered. Chuck Bass had pretty much just committed himself to a relationship, and Blair had to pinch herself to see if she was dreaming. "You know me." She blurted.

"What?"

"You asked if you knew me. You do."

"Do I know you well?"

"Not telling!" Blair pressed her lips together tightly, grinning.

Chuck couldn't help but laugh at her adorableness. "Please?"

"Nope!" Blair smiled. "That's for me to know and you to find out."

A buzz broke the banter. Blair frowned as she pulled out her phone.

"Do you have to go?" Chuck asked worriedly. They were having such a wonderful time.

Having fun with your dark knight?—S

Blair pouted, as she tried not to blush. "No. It's just…It's nothing." She typed up a witty, snide remark before pressing send and setting her phone on the floor beside her.

"Who was that?"

"A friend." Blair scowled.

"Just a friend?" Chuck pressed lightly. He hadn't left the forming tint on her cheeks overlooked.

Blair laughed at his envy. "Yes. I'm very much single."

Chuck pulled a scorned face sardonically. "Single? I thought we were something."

Blair paused. "Are we…you know, something?" She questioned. She pulled at the fabric of her slip nervously, scanning Chuck's face.

"Do you want us to be?" He asked, watching the lines of her face just as carefully as she watched his.

"If you thought of it as one, I would want to know."

They stared at each other for a long time, and Blair sighed. "Of course." She frowned as she adjusted her slip, and reached for her purse. "I should go."

Chuck watched wordlessly as she stood up. A million things to say ran through his mind—we are something. I want to be with you. I love…—but he was impotent, stationary in his position, as she tossed her hair back indifferently and left the rooftop without a glance back.

…

Blair waited until she heard the click of the door before letting her worst thoughts claim her. She collapsed against the door, pressing her mouth against her arm to muffle the sobs, hoping Chuck wouldn't come out anytime soon. This wasn't supposed to happen like this; she wasn't supposed to feel this way. Blair supposed she always knew there would be consequences if things didn't work out the way she planned. But of course, she had ignored the doubts, and pranced along in her perfect world. She was supposed to find Chuck, and have fun. She didn't exactly know that she was going to lose her virginity to him—although, if he ever asked, she'd swear that she had done it before in Paris—and she most definitely did not plan to get her heart broken. She didn't even know Chuck Bass was capable of doing that to her.

After a few moments passed, Blair sighed, took a moment to regain herself, held her head high, and made her way gracefully back down the stairs. She wouldn't let Chuck control her thoughts. She just couldn't.

…

Chuck leaned against the door, pretending not to hear the soft sobs from the other side. He didn't know why he didn't say anything, but he was silently berating himself for not stopping her.

He exhaled leaning his forehead against the metal of the door, feeling the pleasant coolness against his skin. Did he love her? It hurt like knives in his chest when she walked away from him, but was that feeling equivalent to love? Chuck didn't know. It wasn't like love was a normal thing for him. But the sudden realization that he would probably never see her again—aside from run-ins, in which only she would know that she was his princess—sunk in, and for just a moment the instinct to breathe was gone.

"Great." Chuck muttered bitterly, "You've screwed this all up, and now you'll never see her again."

As if in response to his desperate statement, a flash of color caught in Chuck's eye. He looked down to see an orange phone sitting delicately against the pavement, looking almost too perfect in contrast to the grime of the rooftop. Chuck slowly wrapped his fingers around the small device, grasping it carefully, as if the phone were threatening to crumble into dust at any given moment.

Chuck randomly pressed a button, but immediately flipped the phone over, nearly dropping it, after he had done so. This phone held his princess's identity, and Chuck wasn't too sure that he wanted to know what it was. He liked the ambience of mystery. He liked how he could envision her to be whoever he wanted her to be, as perfectly as he wished. When things were left in the dark, much was left for Chuck's imagination. And in this case, he liked to think that his princess was a perfect and pristine socialite who deigned to acknowledge her inferiors' existences.

Knowing who she was could ruin it all.

Keeping his eyes pressed tightly together, Chuck dialed 1 and let the phone ring.

"Hey—"

Chuck cut her off before he heard the name she was about to say. "Tell the owner of this phone to meet me on the rooftop of the Palace tomorrow at midnight."

And then he hung up. Chuck could feel his mind whirring. He tried not to match the voice he had heard with a face. It sounded so familiar, but Chuck knew once he figured out whose voice that was, it wouldn't take long for him to figure out who his princess was.

Chuck tried to forget the familiar voice, as he put the phone in his pocket, smirking. She had to get her phone back, didn't she? He would see her again, and Chuck would be sure to make amends.

Sorry it took so long to update =/ but i really like this chapter, tell me what you think! :)
