It seemed to me that Chakotay and janeway had a much better chemistry going on between them than him and seven. I just wonder why he chose her over janeway.
Because of incredible stupid writing.
Sorry, I've tried to come up with some "Trek Universe" theory but I can't. No chemistry or attraction at all between Seven and Chakotay.
Seven did have an attraction to Chakotay.
It was shown in her romantic holodeck scenarios.
However, it was Chakotay that never showed any interest in Seven.
