Hm, interesting questions, GG.
That is a question of whether Vorik had any true feelings for B'Elanna beyond the 7 year booty call.
It's not very logical that he would be attracted to the volatile personality of Torres. Nor is it logical he would be attracted to engineering skills, though he might dispassionately admire them. What about proximity to her on a daily basis as an attracting factor? An emotional reaction easily explained away. But enough to offset her attractiveness to a Vulcan? If Vorik liked B'Elanna for this reason, he would have spontaneously combusted for Seven.
I think Vorik and Kes would have made a cute couple with some intriguing counterpoints, if few sparks.
