Why would a succubus demon attach to a person?

A succubus demon might attach to a person due to their emotional vulnerability or desire for intimacy, as these beings often feed off sexual energy and emotional connections. They may be drawn to individuals who are lonely, seeking fulfillment, or experiencing intense emotions. Additionally, a succubus could exploit a person's weaknesses or unfulfilled desires, establishing a bond that allows them to draw energy and influence their thoughts and actions. Ultimately, the attachment serves the succubus's need for sustenance and power.
