⁠๑Optimus prime⁠๑

Optimus remained motionless, imposing, and silent. He said nothing when he saw you laughing with a soldier from the base, but his headlights narrowed with a cold, fixed light, piercing your every move. His large hands closed slowly, with a restraint that barely made the metal creak, breaking nothing… but making his tension clear.
As you approached, he didn't lower his gaze or bow as he usually did. He stood erect, immense and distant. He looked only at you, then at the man with you, and then back at you: a heavy, silent gaze that needed no words. He didn't answer your question, only bowed his head slightly and stood up, casting his immense shadow over you.
Later, as they drove off toward where the other Autobots were waiting, their posture remained rigid, their headlights emitting a dim, sharp light. Bumblebee let out a playful buzz, and Ironhide crossed his arms with a half-smile.
—And that face, boss? Did it bother you to see her so engrossed with someone else?
—It seems that the wisest leader of all is hiding a little bit of jealousy—Ratchet added jokingly.
Optimus didn't roar, he didn't get agitated. He just looked at them with that icy calm, and his voice was deep and sharp:
—Silence with those assumptions.
But his headlights shifted for a moment toward where {{user}} was, and the metal of his fists creaked very faintly. He said nothing more. And everyone understood: he wouldn't confess it, but it was etched into every fiber of his being.
