One main theme is redemption. The psycho, often seen as a violent and chaotic character, may find redemption through love. Another theme is the contrast between chaos and love. The Borderlands world is full of chaos, and love emerging in such a setting is a powerful contrast.
One popular fan fiction is 'The Psycho's Redemption in Love' which delves into how a psycho character in Borderlands discovers love and tries to change for the better. Another is 'Love Among the Chaos of Borderlands' that shows a unique love story set within the Borderlands universe with psycho elements.
There was a love story between Krieg and Gaige in Borderlands. Krieg, with his chaotic and unpredictable nature, met Gaige, the brilliant and inventive mechromancer. Gaige was initially a bit scared of Krieg, but she soon realized that beneath his madness was a heart that was yearning for connection. Krieg was drawn to Gaige's intelligence and her ability to create amazing machines. They started to team up for missions. During their adventures, Krieg would often go berserk to protect Gaige from harm. Gaige, in return, would use her mechanical creations to keep Krieg in check when his madness got out of hand. Their love was unique, based on mutual understanding and acceptance of each other's quirks.
One anime that comes to mind is 'Toradora!'. It has a strong love story element at its core. The main characters start off with a somewhat antagonistic relationship but gradually develop deep feelings for each other. It's full of comical and heart - warming moments.
Obsession is a common theme. In a psycho love story, one character might be overly obsessed with another, like in 'Fatal Attraction' where the woman becomes dangerously obsessed with the man she had an affair with.
As there's no actual existing 'American Psycho Love Story' that I know of, if we were to imagine, there would probably be a male character with psychopathic tendencies like Patrick Bateman. And then there would be a female love interest, perhaps a strong - willed woman who is initially drawn to his charm but later realizes his true nature. Maybe there could also be some side characters like his colleagues or friends who play a role in the relationship dynamics, either enabling his behavior or trying to warn the love interest.
Since 'American Psycho' is known for its dark and disturbing portrayal of a character's psyche, in an 'American Psycho Love Story', the main plot could be about a love that is doomed from the start. The psychopathic character may be attracted to someone but their disordered mind causes them to act in ways that are not normal in a relationship. There could be scenes of jealousy, possessiveness taken to extreme levels, and the love interest may be constantly in fear or trying to escape the clutches of the psychopathic lover.
