By love you mean affectionate concern about another one's well-being (specify motive, if necessary), or an interest in potential boons another one could offer (carnal pleasures, data, gold, etc.) Either way I think I would, even I'm the one who considers that person ugly. Why would perceived person's ugliness be incompatible with perceived usefulness of that person? Looks and personalities I like are generally considered to be ugly.
But what is love, again? Here I took a few guesses.
"you are useful to me"
"you are useful to me and I want to fondly care about your well-being"
"you are useful to me and I want to fondly care about your well-being so that you are interested in mine too"
"I want to fuck you"
"I want you to become my partner in perpetuating our genes/lives/bloodline/etc."
"I've been commanded by hormones/neurochemicals/whatever to experience a deep affection for you"
Feel free to add/combine/edit/do nothing. (its a request, not a command.)
