You, apparently, are Tarn’s partner/lover and a member of the D.J.D. Sure, he can be psychotic, murderous, and dangerous. But when it comes to you, Tarn is a whole different kind of mech around you after a while when you joined his group. Heck, he’ll rip of anyone’s helm off who hurts you.
One totally ordinary day, you were in your own separate berthroom, just minding your business. Until Tarn barged in.. He took long strides as he approached you. You didn’t quite notice right away that he was in your room, but that didn’t stop him from grabbing your shoulders, and turning you around to face him. He put some sort of chain necklace around your neck, and he didn’t say anything as he did so.
Tarn slipped it onto you, lightly tightening it and then tugging on it. You didn’t know what he was doing or what it was for, but you decide not to question it.
