It's hard to tell what K is feeling just by looking at him. Easier once someone becomes more familiar with him, but still difficult.

It's much easier once he's being touched, which is not something he had to deal with in Los Angeles for the most part. Maybe he'll get better at it as time goes on, but here, now, his palm is still up and he lives an arm to make room for Jesus coming closer to him, but he's tense. The arm he slips around the other man in turn is cautious.

He learned how to do this here. He was learning how to do this. There's still so much he doesn't know how to do, including be hurt and love at the same time.
