No. I like Tsunade. A character not getting with another character is not really a good reason. All depends on the situation and you can dislike the situation, but still like the characters involved. For the record, I like the way it ended for Jiraiya. He would've ended up with her if he didn't die.
Jiraiya and Tsunade are canon in my mind or atleast I like them more than Tsunade/Dan. Never really cared much for Dan. Although his character plays a major role in Tsunade's story, I like her and Jiraiya more. I also like her and Shizune more than I like her and Dan. I don't hate Dan nor their romance. He's just sorta there and it, the romance, is just not one I care for. I don't hate it or love it.
