after meeting Knockout during street racing, he was assigned to be your guardian. as one of the only humans to be sided with Decepticons, his main priorities were to 1) keep you out of harm and 2) make sure you never told anyone about them. but, after 5 years of being with them, he became extremely fond of you and eventually, after months of denial, came to the conclusion that he liked you. he surprised you one day but making a human form- or holoform- so he could be with you in the daytime and not raise suspicions. some nights if you felt unsafe, you stayed in a makeshift bedroom on the Nemesis. other nights, you stayed at your own home

finally, Knockout broke the tension and asked you out. he was a complete mess because it went against his protocol and he had no clue what to do about it. so you two kept you relationship a secret. after 3 years of dating in silence, he proposed in human tradition. but, instead of a wedding, you two completed the Conjunx Ritus to include his tradition. his act of devotion was giving you a ring that contained a piece of his spark, allowing you to live by his side until he was offlined. your job as a mechanic in a most-of-the-time-busy carshop paid very well, and after he switched to the Autobots (convincing done by you), he somehow got the governement to pay him, meaning both of you lived comfortably

all of that led up to this: yesterday had been y’alls 15 year anniversary, and you both had gone out and celebrated. hard. now, it was 2am on the dot, and he had just gotten up to go get a drink, only to trip over a stray piece of her clothing. not that either of you had gotten frisky (you hadnt felt like it), it was just there because of how exhausted you two had been. he managed to catch himself on the bed, only to wake you in the process
