A/N Yes, the title is from Hamilton but it just fit this story so well, I had to use it.

This story is AU and is set in NY. Kurt and Blaine met in high school but we're only friends. Kurt never went to Dalton so they remained best friends and went off to college together (they are the same age in my fic), and are roommates. This is one of those oblivious Blaine fics and it does include Sebastian but is not Sebastian friendly. Klaine are and always will be endgame.

Chapter 1

Blaine Says Yes

Kurt was standing in the kitchen rinsing out his tea cup when Blaine returned home from seeing Sebastian. The door slammed and Blaine was suddenly in the kitchen bouncing up and down.

"Guess what?" He said happily. "I'm getting married." He continued quickly, not waiting for Kurt to respond.

"You're what?" Kurt screeched, turning around so fast he almost knocked himself over with the force.

"I... well, I'm engaged." Blaine stuttered as if he was unsure. Kurt's eyes were wide and his head was spinning. He had to have mis-heard.

"I thought you and Sebastian had broken up again." Kurt said, the distain evident in his voice.

"W-we were just taking a break, but he asked me to marry him last night and I said yes." Blaine replied, his voice shaky.

Kurt just stood there staring at his best friend and hoping he'd just wake up from this horrible nightmare. Blaine and Sebastian had been dating on and off since their freshman year of college. Kurt hated Sebastian from the beginning, which put a severe strain on his and Blaine's friendship for a while and with them being roommates, it made things even worse.

It got so bad that Kurt decided to move back to Lima for the summer and work at his dad's garage. He'd missed Blaine terribly but he just couldn't watch his best friend (who he also happened to be totally in love with), date someone like Sebastian.

It was easy for Kurt to see Sebastian for who he was, but Blaine was so starved for love that he was easily manipulated by Sebastian's supposed charms. Kurt made it a point to avoid being home when the two of them were there, which thank goodness, wasn't very often. Blaine knew Kurt hated Sebastian so they usually hung out at his dorm when he graced Blaine with his presence, which wasn't much after school started back up again.

"Tell me you're kidding." Kurt said forcefully, eyes darting back and forth across Blaine's face trying to sense any hint of humor. His stomach dropped when he realized it wasn't a joke.

"Please, just tell me why? What would possess you to say yes to him? What does he have? How can you continue to go back to him after how he treats you?" Kurt pauses, seeing the pain on Blaine's face, but he's so angry that he can't stop. "Did he hit you again?" He knows he right the moment Blaine drops eye contact.

This would normally be the time when understanding Kurt would come out and he would go over and hug Blaine and wipe his tears and support him no matter what. But that was not happening today. Kurt was over it. How in the hell could Blaine agree to marry someone that would hit him?

He froze as the realization hit him and as he looked down at Blaine's finger, his suspicions were confirmed. Rage burned inside Kurt and he just couldn't hold back this time.

"Oh my God. How can you be so stupid." He said in a tone of voice that made Blaine shiver, watching Kurt with curious eyes. Kurt shook his head. "Don't you see? You went over there to get your stuff. You told me you were done, although you happened to leave out the little tidbit that he'd hit you again. Because you knew I'd never let you go alone, right?" Kurt could see he was right by Blaine's body language.

"So what, you go over there and he sweet talks you, tells you how sorry he was, then what, you cave?" Blaine doesn't even have to respond anymore because Kurt knows him so well that he can read every sign from Blaine's mannerism. "Wait, you didn't cave right away." He starts pacing back and forth in front of Blaine. "You were holding strong and he got scared, so he proposed."

When he stopped for a moment and looked at Blaine he knew he was only partly right. Kurt barked out a laugh. "He didn't even propose, did he? He didn't ask, he just demanded. Said, hey, we'll get married and then you'll see that I am truly sorry, right?" Kurt didn't even have to look at Blaine to know the truth this time.

"Don't you see?" He said, finally turning back around to face Blaine. "He has no intention of marrying you. He didn't have a ring, nor did he get down on one knee and ask you. He just said what you wanted to hear so you'd take him back. Oh my God. Blaine, please tell me why you said yes."

Blaine was a beautiful disaster, standing in front of Kurt in their living room, tears running down his face, shaking from trying to hold back his sobs, but Kurt couldn't bring himself to comfort him. Not this time. He just waited for a response.

"What if he's my only chance?" Blaine says so quietly, Kurt almost doesn't hear.

"Your only chance at what?" Kurt asks, afraid to hear the answer.

"Love." It's said so softly, it's almost like he's letting out a breath and not a word, but Kurt heard it anyway, and when he did his heart broke into tiny pieces. Was Blaine so blind that he didn't see what was literally right in front of him?

The part of Kurt that cared was gone and what was left was a shell. He had loved Blaine since they'd met and continued to hold out hope that Blaine would finally see Kurt as something more, but that time was over and Kurt was just hurt.

He stood there for a full minute, maybe more, and just stared at Blaine. He could tell that Blaine was hoping Kurt would hug him and comfort him, but he just didn't have it in him anymore. He thought he'd be angry, but he just felt resigned.

"Are you blind?" Kurt finally asked, his voice flat.

"What?" Blaine asked, clearly not understanding.

"You must be blind if you can't see that I love you." Kurt replied, but again, Blaine didn't fully comprehend what Kurt was saying.

"I know you love me, silly. You're my best friend. But I'm talking about romantic love. Forever love." Blaine said.

Kurt stood stock still in front of Blaine and just sighed. This is not how he thought this would go, but he just couldn't do it anymore, so with tears running down his face, he opened his mouth and told Blaine exactly how he'd been feeling for the last few years.

"I know all about love." Kurt said quietly, and Blaine's eyebrows shot up in surprise. "I've been in love with you since high school."

The silence in the room was deafening and with every second, Kurt died a little inside, so he broke the uncomfortable silence, as well as his heart.

"I know you don't feel the same way, and that's ok, but I can't stand by and watch you marry someone who hits you and doesn't even know the meaning of the word love." Blaine opened his mouth and looked like he wanted to speak, but Kurt cut him off with the wave of his hand. "I'm going to stay with Rachel for a little while and let you have your space." He turned and walked toward the door, grabbing his coat and keys on the way. He didn't turn back around, because he didn't want Blaine to see the look of devastation on his face, not realizing Blaine was wearing the same look.

He paused in the open door, his back still to Blaine and said softly, "Let Rachel know when you've moved in with Sebastian so I know it's safe to come back." He then shut the door quietly. He waited until he was in the elevator before he let out the sobs he was barely holding in.

Blaine was in shock. Had he heard Kurt correctly? Was he really in love with him? His thoughts were all a jumble and he had no idea what was happening.

He'd just come from Sebastian's and was so happy. At least he thought he was. But deep down he knew something wasn't right. And when Kurt called him out, he'd gotten scared, because everything Kurt said was true. In his heart he knew Sebastian didn't really want to marry him. He'd told him so over and over again, but when Blaine heard those words come out of Sebastian's mouth, all he could think of was 'This is what I always wanted.' But was it really?

He'd thought so at the time, but Kurt always made him see everything so clearly. He kept Blaine grounded. He was his best friend. How could he have missed the fact that his best friend was in love with him?

But how did he feel about Kurt? Of course he loved him. They'd been best friends since high school and Kurt was the most important person in his life next to...well, next to no one. His parents didn't really care and his brother was wrapped up in his own life. And Sebastian, he'd made it clear that every other thing in his life was more important than Blaine.

As he stood watching and listening to Kurt go on and on about Sebastian he saw Kurt angry, as he always was when Seb was involved. But once he admitted how he felt, he immediately saw Kurt transform in front of him, the light leaving his eyes and that made his stomach turn and his heart heavy.

There were so many emotions swirling around in him that he wasn't fully aware Kurt was leaving until the door was shut and Kurt's last words ringing in his ears.

He fell to his knees the moment he heard the click of the door, tears running down his face. His breath was coming fast and he felt like throwing up at the thought of Kurt not being there anymore. Not to mention living with Sebastian. That was not an option. He was never even allowed to spend the entire night there. They had sex and he went home. No cuddling, no post coital glow.

As much as he hated to admit it, those were the nights he always craved Kurt's attention and cuddles. The thought that Kurt probably knew he'd had sex with Sebastian and came home and cuddled with him on the couch (even though he was in love with him), now made him literally sick, and he jumped up and bolted into the bathroom.

He needed get his head on straight and to talk to someone, so he grabbed his stuff and went to Sam's.

Blaine arrived at Sam's 15 minutes later and was standing outside his door, shifting his weight from foot to foot in anticipation. Maybe he should have called. What if he wasn't home? He really needed to talk to someone. He quickly knocked before he could freak out anymore and was so relieved when Sam opened the door.

"Hey man, what's up?" Sam said, stepping back and letting Blaine past him before closing the door. He'd noticed how pale his friend was and was worried. He knew about Blaine's problems with Sebastian and had tried over and over in the beginning of their relationship to get him to listen, to no avail, so now he just tried to be supportive. But it was usually Kurt who was there for Blaine, so Sam was even more concerned.

Blaine walked over and sat down on the couch immediately putting his head in his hands which did nothing to calm Sam's fear.

"So, what's up? You ok?" Sam asked, taking a seat next to Blaine. "Did Sebastian..." Blaine's head shot up at his question and he stopped at the look on Blaine's face.

"No, it's, um, it's Kurt." Blaine stuttered. Sam just looked at him as if to say, go on. "He, uh, he said something really weird today." Sam just sat and waited for Blaine to finish. "He told me, geez, he told me that he was in love with me."

The look on Blaine's face was classic and Sam actually laughed. "So, he finally told you, huh?" Blaine's mouth dropped open.

"W-what do you mean, he finally told me?" Blaine said, obviously in shock at what he was hearing, and Sam shook his head.

"Blaine, man, he's been in love with you for years. Are you seriously that oblivious? Did you really not know?" He looked at Blaine's face and his shoulders slumped in defeat. "I really thought you knew and were just pretending."

"P-pretending what?"

"To be clueless." Sam replied.

"N-no, no, I wasn't pretending anything. I really didn't know." Blaine got up and started pacing around. "Why?" He looked at Sam still sitting on the couch, hoping he had all the answers. "Why didn't he say anything? I mean, we've been best friends since high school. If he had feelings for me, why didn't he say anything then?" Blaine was getting worked up and continued to pace back and forth in front of Sam.

Sam shook his head and looked up at Blaine with a stern look.

"Seriously? Do you remember high school?" Blaine stopped for a moment and thought back to high school. Blaine had gone to Dalton and Kurt to McKinley and the two had met at a show choir competition where Blaine had found Kurt leaning up against the wall in the back room crying. Blaine stopped and comforted the broken boy and had felt an instant connection then.

He could see the signs and knew Kurt was scared of something or someone. He had an overwhelming urge to protect this boy in front of him, so they exchanged numbers and became fast friends, sharing stories of their pasts and connecting on everything from bullying to singing.

Kurt eventually told Blaine what had happened with Kurofsky and Blaine jumped eagerly into the role of mentor. He loved being the 'knight in shining armor' who was there to help 'save' people. And that's how he became Kurt's Knight. Blaine looked back at Sam after reminiscing, a slight smile on his face.

"Of course I remember high school. We became best friends right away and told each other everything. So why didn't he tell me he had feelings for me?" Blaine asked, still confused.

"Blaine, think about it. What did you guys talk about in high school?" Sam said, with a slight irritation in his voice at not getting though.

"I don't know, just the normal stuff. Vogue, fashion, musical theatre and our show choirs, song choices...boys." Blaine said smiling.

"Exactly." Sam said, looking pointedly at Blaine. "Now think...who was it that talked about boys?"

Blaine went back over to the couch and sat down, thinking back once again to when he and Kurt would talk about boys. The only person he ever remembered Kurt talking about was...Kurofsky. Huh. He couldn't remember Kurt ever talking about having crushes or liking anybody.

Sam laughed at Blaine's expression.

"Yeah. You see?" Sam said pointedly. "For you it was always 'oh Jeremiah, or oh Lucas, or hey Kurt, you should see so-n-so at the food court.' You always had a crush on someone. A different someone. All the time. And you would always talk to Kurt about them. So of course, he wasn't going to say anything to you about his feelings. He was sure you didn't feel the same." Sam shook his head. "We all thought you did, at first. I mean, you two were inseparable and we thought for sure you'd end up together. But then a year went by and two, and still nothing."

Blaine just sat there and stared at Sam's confessions, trying to take it all in. Sam let out a harsh breath.

"He wanted to invite you to Prom, you know?" He looked over at Blaine, hoping he was listening really hard to what Sam was saying. "We tried to talk him into it, but he was too afraid. He didn't think he was good enough for you."

"What?!" Blaine gasped, his head snapped up and he stared at Sam with an unreadable expression.

"Blaine, come on. You went to a private, prep school. You had all kinds of money and tons of friends. You were surrounded by boys all the time. Everybody loved you. You were the center of attention everywhere you went. What was Kurt?" Sam shook his head. "He had it rough. You of all people know that. Finn, Mike, Puck and I did our best to protect him, especially after we found out everything with Kurofsky, but it still wasn't easy for him. But you, you had everything he wanted and couldn't have. You were everything he wanted and couldn't have. So he decided it was in his best interest to just be friends with you. He couldn't take the chance he'd lose you. You were too important to him."

Blaine sat back and threw his head back against the couch cushion and groaned.

"Oh my God. How could I have been so stupid?" Blaine whined.

"I don't know if stupid is the right word." Sam said and put his hand on Blaine's knee. "Maybe oblivious."

"I was. With everything. And Sebastian." He moaned again, his stomach churning just thinking of his name.

"Yeah." Sam said, his voice hardened a little. "Do you remember your freshman year, when you met him?"

"Of course. Kurt hated him right away." Blaine said suddenly feeling guilty.

"Well, he did, but not just for the reason you think."

"He saw through Sebastian, didn't he?" Blaine said, his voice cracking.

"We all did. But Sebastian made Kurt's life miserable. Everytime you turned your back Sebastian was in Kurt's face about how he wasn't good enough for you and you would never love someone as girly as him. He told Kurt he was going to do everything he could to keep you two apart." Sam sighed. "Blaine, the reason he went after you in the first place was to get to Kurt."

Blaine's head shot up quickly and his eyes widened.

"What?! Why?"

"Back at freshman orientation, when you and Kurt were standing there together and being your normal flirty selves, he saw you. He saw how Kurt was looking at you and so he used you get back at Kurt."

"But why? What did he have against Kurt? He told me they didn't know each other." Blaine said, his voice shaky because he knew in the pit of his stomach that Sam was about to tell him something life changing.

"Well he was a liar. Over the summer, Kurt and Sebastian tried out for the same part in the fall musical and Kurt got it. Sebastian was pissed and hated Kurt for it, so when he saw the two of you together at orientation, he could see it, hell everybody but you saw it. And Sebastian used that and went after you."

"Oh my God, I'm so stupid. How could I have been so stupid?" Blaine put his head down into his hands and closed his eyes trying to hold the tears inside. Sam scooted over and put his hand on Blaine's back, rubbing small, comforting circles.

"Don't be too hard on yourself, man." Sam said softly.

"Are you kidding?" Blaine said, jerking his head up again, looking at Sam with frantic eyes. "Are you kidding me? Don't me hard on myself?" He let out a hollow laugh. "He used me, for over a year, he used me. And all this time, he was laughing and rubbing it in behind my back. Oh God." Blaine said, the pain in his voice was heartbreaking. "That's why Kurt went home for the summer, isn't it? It wasn't because he couldn't stand seeing me happy. It was...Oh God." Tears started pouring down Blaine's face before he realized he was crying. "All those horrible things I said to him."

Blaine put his head back in his hands and sobbed. He was trying to talk and Sam could make out most of it, but feeling the pain coming off of his friend in waves was almost overwhelming.

"I hurt my best friend over and over again for some guy that I thought loved me. I thought he was the only person who would love me, when all along..." Another sob ripped through his body and Sam just continued to rub his back, helping the only way he could.

"It's ok, man." Sam said when Blaine calmed down enough to hear him. "Kurt will forgive you."

"He shouldn't." Blaine said, so quietly Sam almost missed it.

"But he will. You know Kurt. What happened anyway? What made Kurt finally confess his feelings? Did you and Sebastian finally break up for good?" Sam said with a hopeful voice.

Blaine shot up quickly and ran into the bathroom, throwing up for the second time since Kurt left. Sam sat on the couch, puzzled. He waited, listening as Blaine flushed the toilet, turned the water on to rinse his mouth and splash water on his face, before returning to the living room and taking his place next to Sam.

"What have I done?" Blaine whimpered. Sam just leaned over and pulled Blaine to him, showing him support however he could, and just waited for Blaine to elaborate. Blaine just sat there, soaking in the warmth of his friends arms, yet wishing they were his best friends. He appreciated Sam's support but he wanted Kurt. The feeling of warmth that ran through him at the the thought of Kurt's arms around him stunned him.
