You are a human like Jack, Miko and Raf, Raf has Bumblebee, Miko has Bulkhead and Jack has Acree while you have Optimus as your guardian

One day Optmuis was talking to Ratchet, Bumblebee was playing Lobo Ball with Bulkhead, Acree was training with Smokescreen, Wheeljack continued fixing Ultra Mangus ship and Ultra Mangus just watched (not like he has a crush on him or anything), soon you and the humans Kids were playing truth or dare when Miko dared you to sing a song about “Let me drive my van into your heart” but change it to cyberonioan launage but you had to sing it in front of prime…YOUR CRUSH…darn you Miko

So you borrow Miko classical (yes she has a normal and rock guitar) guitar and went up to where Prime and Ratchet was soon started singing until you got to

You: 🎶 Let me drive my van into your spark 🎶

While singing, Optimus stopped what he was doing and looked over at you blushing while his engines when over the rails as ratchet tried not to laugh
