(If you don't know what a Techie is, it's a person that generally works around technology and in this transformers case, they have highly advanced weaponry and devices as well as being a highly valuable bot for their intelligence)

Arcee had gone through partners before, there was three that she blamed herself for; Tailgate, Cliffjumper and (y/n). Both Tailgate and Cliffjumper was offlined by cons, as for (y/n), his fate was unknown. Arcee had feeling toward the trigger-happy mech. When ever she was under heavy fire, the (a/c) colored mech would appear out of nowhere, saving her.

Arcee was already scarred from being powerless to save those two, she didn't want to think that her missing partner was off as well. (Y/n) was too hard of a bot to defeat, let alone a mech who had advanced equipment at his disposal. He was a techie; intelligent, clever, heavy duty, caring, anything you'd want in a Cybertronian sparkmate, though she never got that far with him.

(Y/n) had already lost his sweetspark to Arachnid; his mate had sacrificed herself for his spark; so he didn't want go through that again. So Arcee didn't bother telling him of her love for him, in fear that he'll laugh at her or become mean towards her, leaving her to defend herself.

Now Arcee is on Earth, with a team that cares and protects her as she dose to them.

*time skip to wherever Arcee is...*

Arcee was running from decepticons as they had ambushed her, getting hit pretty bad. She was outnumbered 1 to 15+. Add the fact that her comms couldn't pickup any signal to call a groundbridge, cause' of this, Arcee was stuck and defenseless against them.

The blue bot cursed in Cybertronian before finding a spot to take cover from the gunfire. Losing energon quickly, Arcee tried to stop it by covering the opening on her side.

"This can't be the end for me"

"That's cause it's not" And with that, the gunfire stoped. Arcee didn't know if that voice was real or just in her processor. Coming back to her senses, she felt somebody touching her wound, gasping at who was helping her.

"(Y/n)!!" Said mech smirked

"Yeah?" He said, with a shit eating grin. "Need somethi-hhmff!?" Arcee shut the (a/c) mech up by kissing him, (y/n)'a optic grew wide at her action, but just let it happen. The 2 wheeler pulled back and blushed shamefully.

"Sorry, I-I just didn't think I'd e-ever see you again..." Arcee looked away, silently cursing at herself for being so reckless. (Y/n) chuckled, continuing to patch her side up, then turned her helm to face him.

"I didn't know you fell for me that deep," he chuckled again, taking her in her form. "If I had known sooner, you wouldn't need your nerdy partner to save you, now ant' that right?" Arcee sigh in relief, chuckling at the old nickname she had called him long ago.

Arcee heated up and looked away again, glancing at the mech in front of her every now and again. "Do... do you mind if I kiss you again?"

"I wouldn't mind~" (y/n) replied, getting close to her face-plates.
