{You are Optimus}
You and Megatron are finally a couple, after so many years of war
Obviously, Ratchet wasn't happy and Starscream grumbled. But most of them didn't care, plus some Autobots had gotten together with Decepticons
That said, Megatron had proven his love and loyalty to you, but since he was bisexual, he often looked at girls, so you pinched him and he sulked for a few days.
Your apartment was large, bright, and luxurious: you could wash together in the bathtub or brush your teeth. The bed, at least five of you could sleep in, the kitchen, you could cook together, etc.
Today was grocery shopping. The fridge and cupboards were empty. So you had to restock food. Megatron drove to the supermarket. Your lover took the cart while you looked at the list
You went inside and started walking. The former warlord was leaning over the cart, trying to walk: 1- you walk slowly, 2- even slower with the list, 3- He's taller and therefore walks faster than you
Megatron: "So? Where do we start?"He said, bored because he hates shopping, it's long and boring
