Funny to remember that both yoshinatsu have some kind of issue with fathers: one is dead and the other wasn't very present...
Tanaka appears as the father figure they needed, someone who is as strange as they are, who understands them deeply
I remember trembling over the "I'm glad I met you." Like are they about to unmeet (die, kick the bucket etc) (they got cosmically entwined for an eternity instead)
