You and Optimus were walking in the forest and you were scared that Optimus was going to break up with you.

"Y/n, there has been something that I need to tell you." Optimus said as he stood in front of you.

"Yes?" You asked Optimus.

Suddenly Optimus got down on one knee and pulled a little blue, velvet box out of his pocket.

"Y/n, you are the most beautiful, kind and amazing human I have ever met in my entire life, you stayed faithful to me even after I sacrificed myself to fully restore Cybertron, you also are the reason my spark warms up whenever you are around, F/n, M/n, L/n, will you do me the honor of becoming my sparkma- I mean wife?" Optimus asked you as he opened the box.

You cried when you saw the engagement ring in the box that Optimus held after proposing to you.

"Yes Optimus, I will!" You said as you cried.

Optimus slipped the ring onto your ring finger and you hugged Optimus tightly and kissed him.
