Optimus Prime, your Sparkmate, who was always on missions and fulfilling his responsibilities and didn't have time to talk to you or offer you any affection.

at first, you understand that he couldn’t spend some time with you since he was the leader of the autobots and needing to do his duties..but this had been happening for months now of not spending some time alone together.

you decided to talk to him about it, so you watched Optimus talking with Bumblebee until he finishes.
