The moment the scout of the Autobots laid his baby blue optics on (y/n), his world had more meaning than he originally thought. Sparkmates were 1 in a million to find, even harder since Cybertron fell. Not many even got to find their mate at all. But Bumblebee knew that he had to keep her close.

For now, Ralf and (y/n) were doing computer work at the front of (y/n)'s house. "(y/n), could you send me the 211468 code patch?" The younger boy asked his older friend.

"Yeah, let me go over it to make sure it's bug free." (y/n) responded.

"Take your time."

Bumblebee was in his alt while he watched over the two. (y/n) didn't know about him, but she did know that the vehicle drove Ralf to and from school; to other places that she wasn't allowed to know about. But it was hard for Bee as he must not attract attention to himself. The human girl was his mate, but she didn't know.

"Okay, sending the code patch now. Would you be able to look over it in case I got it wrong?" (Y/n) sent the code to Ralf and looked his way. She grabbed her bottle of water and took a gulp. The boy nodded as he kept working on a program for the Autobot's main computer. The (h/c) teen girl was only 3 years older than Ralf and was out of school early. She knew so much about things and such that the school had to let her graduate early.

"It's perfect, thanks for doing that for me and my friends." He replied, glancing at her and nodded.

"Not a problem. Anything that'll help you or them out." (y/n) grinned, unknowing that the smile was making Bee flush at her adorableness. It got the best of him and he let out a long quiet string of buzzing. The female human was too busy concentrating on fixing up some codes to hear it, but Ralf could hear it clear as day. The younger child looked to his vehicle in question, to him it sounded like Bee was glitching. Since it sounded like...

:Aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa:

Eventually, (Y/n) started noticing this low sound and looked for the source. Bumblebee instantly stopped when her gaze met his form, his spark acted up, trying to get to her but failing.

"Hey Ralf." (Y/n) looked at her friend from the corner from her (e/c) eyes. "Is one of your 'friends' here?" Ralf looked to (Y/n), then to his laptop. He didn't want to admit it as it would get him into trouble for telling. But considering that she already knew about the whole thing behind their backs, he thought it would be better not to lie when it was clear that the answer was right in front of her.

"Yeah..." Ralf admitted, sighing tiredly.

"Huh." She looked back at the black striped, yellow Camaro in thought. Bumblebee decided to speak up, knowing he'd been caught.

:Uh, h-hi...?: (Y/n) was a little shocked, but barely. After a moment, the human nodded to him.

"Hey."
