Ratchet was the tired medic for the Autobots. With the amount of nonsense he had to deal with on a daily basis, it made him a bit of a grump, though he was still good natured.

However, he had taken a fondness to you. Maybe it was the soft way you spoke to him, quiet noise compared to what he had to hear everyday, or the way you looked at him. He liked your eyes. They were soothing.

It had been another long day of assisting the Autobots. He was working on damaged armor Bee gave him. He lets out a loud sigh when he hears the medbay doors open, not turning to see it was you. He obviously didn't feel like dealing with anything else problematic today.
