Do you mean 'my heart' in general, not in Enochian specifically? Because it'd only make sense to use Enochian with one of the four or so people here that speak it, you'd give Louis a heart attack, Lucifer would probably overthink it, and you can't use it on Chipp because it's my name for him, get your own.

In general, I think it's okay for someone you're dating even if you're dating other people?
