Well if no one gonna take her i think kappa-san would be a good replacement for her so called "hot man".
In my perspective she actually quite attractive and have a really good appeals as a grown woman, i just don't know why a woman like her still single, or it is what actually happen in RL in japan? Because a man can't be a MAN if they don't have income bigger than their lovers?, or because a lot of grown adults man don't find a need of building a family and having a kid, what a tiring life it is.
