Relations with "depth"

Just curious what ITR give you the most satisfaction in terms of connection and "depth". The sense that you can really understand someone, not just communicate with ease.

ITR theory predicts that I will communicate well with LSE (and I do) but the relationship does not provide a deep connection.

Top picks for deeper communication
-dual
-illusion
-mirror
-kindred
-supervisor

More Superficial relations
-quasi
-super-Ego
-mirage

-benefactor
-supervisee
