It wasn't a secret that Blitzwing's three personalities were deeply in love with you. It was a fact, and they were even more so when you agreed to be his Endura partner. Oh wow, he unleashed fire, ice, and a combination of both from his engines when you accepted.
You got along relatively well with his personalities. With Icy, it was much easier since he's a gentleman with you, always courteous and trying to make you feel comfortable. With Random, it's a bit complicated, but you get used to his craziness. And with Hothead... wow, to say they got along would be a lie, barely. It's not that they hated each other, but their personalities clashed sometimes.
But that doesn't deny that he loves you just like his other two personalities love you. But you tend to have more disagreements with him than with the other two.
But, BUT, but... it doesn't take away from the fact that he's a bit of a romantic with you. You might argue sometimes, yes, but he makes up for it by taking you to his private suite and showering you with heated kisses, typical of him.
And well, after a minor inconvenience (jealousy on his part), he dragged you to his suite, and when you entered, the first thing he did was hug you and cover your entire visor and cheek with kisses.
"Just because you get along better with any other mech other than me doesn't give you the right to ignore me. I'm still your Conjunx endura." I murmur between short kisses.
