Best Friend 1/2

After their first meeting – technically second, but Blaine refused to count that day seven years ago –, Sebastian and Blaine soon met again. Blaine decided to join the Warblers after several Warblers had told him about it and convinced him to join. They had heard him sing behind the piano one day and told him they would sound much better with him in the mix. When he first started this school he'd planned to stay in the shadow as much as possible. He didn't wanted to stand out from everyone else, but he soon realized that he loved to perform.

His parents have told him that he has an amazing voice ever since he turned eight. Of course, in the beginning they just wanted to be nice, but soon they were speaking the truth.

He had more friends than that he could ever dream of and he felt at home. In the beginning it had been hard. The scars had still been on his stomach and shoulders from the beating at the Sadie Hawkins Dance at his old school, but when they faded away he could move on with his life, thanks to all of his friends and family.

Months passed and Sebastian and Blaine became much closer friends. They laughed and talked.

Whenever people told them to marry already Blaine would blush and Sebastian would make a snarky comment about how he had way other plans with Blaine. Blaine loved the flirting. It made him feel special. He may not understand why Sebastian would wink at him all the time or why he calls him Killer, but he likes these little things. It's something for Sebastian and Blaine.

Or Seblaine, how the Warblers liked to call the two of them. They were literally inseparable.

At least until a boy named Kurt Hummel decided to stalk the Warblers and Blaine couldn't stop talking about him.

"Bas?"

"Yeah?"

"You think he's okay?" Blaine was playing with the sleeves of his blazer as he stared at the pages of his Science book, not taking in a word that was written on it. When he met the boy earlier this week he couldn't stop thinking about him. He had given him his number and over an hour ago he had send him a message, but he'd never texted back.

Sebastian frowned and he turned away from his homework to look at Blaine. "Who?" He asked.

"Kurt."

"Who's Kurt?"

Blaine looked up with an annoyed – almost angry – expression on his face. He finally closed his book and reached for his phone. "Not funny."

"Why are you so interested in him anyway? It can't be his looks, because damn, that boy has a fucking gay face."

"Not everyone is interested in just someone's looks. And besides I think he looks… cute." Blaine said as a blush crept on his cheeks. "But that doesn't matter! I just wanna know how he's doing. He reminds me a lot of myself when I went to a public school."

Sebastian smiled, but on the inside he felt anger, maybe even jealously. Not that he'll ever admit that aloud. "You're sure you don't have a little crush, Blainey?"

Blaine giggled and threw his Science book towards Sebastian. It landed perfectly on Sebastian's lap, and Blaine let out a loud sigh. He fell down on the bed and stared dreamingly to the ceiling.

And even though Sebastian had expected this answer, he couldn't stop be disappointed.

Blaine was his, after all. Well... in his head he was.
