Could you do either a prompt or headcanons for Sunstreaker/Bumblebee?
They're both pretty upbeat, outgoing bots, but Bumblebee is definitely the more responsible of the two. He has all the brain cells in this relationship.
Sunny is lazy when he wants to be, but Bee doesn't tolerate it for long. He'll make Sunstreaker help with chores. He's developed a Look that works every time.
The last time Sunstreaker failed to heed the Look, his armor flaked for two weeks.
Sunny complains but he actually doesn't mind helping that much (if it's Bee, anyway) especially since Bee's little hands are so good at helping him clean and polish all the hard to reach places that even Sides has trouble with.
They do love each other, they just fuss over and spoil each all the time. Sunny is actually the mushier of the two, much to everyone's surprise.
Sunstreaker absolutely teases him for his height every day of his life and Bumblebee is one joke away from killing him for it.
