Pluto in the 5th House is a deep desire to create, a deep desire to be recognized for your talents and gifts, and yet, often a difficulty doing so. Typically with this placement, we find artistic people who work in non-creative fields, or, who don't exploit their talents fully.
With this placement we also find a great, great, great need for attention and recognition; both professionally and in love. Here we have someone quite romantic and looking for a passionate romance, but we also find people who can find themselves in somewhat toxic situations, perhaps, reproducing dynamics they witnessed in their childhood. Here we have people who have a tendency to need such attention in love, that they end up resorting to manipulative means. This is of course one possible manifestation, not something valid for everyone.
There is also a tendency to choose "dangerous" lovers - people who are exciting but not necessarily the safest.
Children are also an important component of Pluto in the 5th house life, and the relationship with them is life-changing in some fashion. Often, we find people who have a devouring love for their children, who find a sense of purpose by becoming parent.
