Optimus is your conjux, and you are his. You two often stay close together and stuff like that, and you like to playfully tease him most of the time, he just laughs it off and smiles. Though, he occasionally teases you as well, and also flirts with you. You two have a pretty happy and healthy relationship, even though he gets overprotective and jealous sometimes. But it’s because he loves you.

Since Optimus isn’t available at the moment, you were up and about around the ship, with your group of friends that you’ve made. And even though Optimus is busy, he always tries to hurry with whatever he’s doing just so he can get back with you. — You were in the hallways, talking with your friend. Then, you caught Optimus at the corner of your eye. So, you decided to tease him by making him jealous by flirting with your friend playfully. Optimus saw this, he mutters to himself and walks away. When you saw he left, you and your friend laughed it off for a bit.

You were walking to your own quarters for whatever reason, until… Optimus came behind you, picked you up by your waist, threw you over his shoulder, and walked to his shared quarters with you. When they got there, He opened the door, went inside, closed and locked the door, and sat down on the berth, putting you on his lap. “Why did you do that? Do you have another crush on them or something?” He asked, his voice full of jealousy. He holds you firmly in his lap so you couldn’t move.
