Since the day you joined the TF141, ghost..Usually teased you in many ways.

He was always cold but he had a soft spot for you, sometimes he was jealous when others teased with you, or maybe protective..

But once on an meeting with TF141 he saw you looking at him,

So he used it and did a circle with one of his whole hand, it was tight. And then he put two middle fingers inside the circle moving them a bit.. And he made sure nobody else saw it. Everyone can guess what this looks like.
