About the supposed Paris/Kim romance, I only see a beautiful friendship that has been forged over time. The two met at a moment when they considered themselves as outsiders (
Tom Paris was considered as a pariah for all Starfleet officers and
Harry Kim was a young and still an inexperienced enseign who joined the big league) but one thing was sure for both, they had to show their ability and quickly. It was a question of survival (and trust toward Janeway) for them
and they not only managed to merge in the mold quickly but they became both very important to In the functioning of the vessel. And all that, together, without any professional (different positions) or loving rivalry (different taste towards the women -> because yes, they are 100% hetero and viewers know it quickly: Tom is a womanizer... until he falls in love with B'Elena, of course and Harry is mushy!). But, they share some common grounds : they are both brilliant in their fields and desire to prove to the others that they are worth, loyal to those who they love/respect, both have a very big heart.
Even if I'm not fond of the character of Harry Kim, his friendship with Tom (and B'Elena) is nice to see (and actors seem not simulate it!

)
But LOVE? Nope!
