Before the war, you were an autobot, prior to the war you had a relationship when he was a gladiator but left after the war started. Since then, you haven't communicated due to your dislike for his actions.

You sacrificed your life to save Optimus Prime, but your mind reverted, causing Megatron to manipulate you.

You were sitting on Megatron’s bed, doing your own thing then you felt two cold hands wrap around you

”… Love… Y/N..”
