Twisted plotlines. There are often unexpected twists and turns that are related to the love relationships. It could be a sudden revelation about a character's past that completely changes the dynamics of the love story, or a character making a drastic decision based on their warped view of love, like faking their own death to keep a lover or something equally extreme.
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.
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 characteristic is complex characters. In these novels, the characters often have 'psycho' traits, like extreme shyness or over - the - top confidence which lead to comical and interesting love situations. For example, a character might be too shy to confess their love but overthink every little interaction with their crush.
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.
Love can co - exist with a negative perception when there are other factors at play. If the president has some redeeming qualities like a strong sense of justice in certain areas, the person can still love him while acknowledging the 'psycho' side. For instance, he might be tough on crime which is seen as a positive by many. So the positive and negative can be compartmentalized in the person's mind.
One example could be 'Gone Girl'. It has elements of a rather 'psycho' relationship with twists and turns in the love story. The characters' actions and the way their relationship unfolds is both complex and somewhat disturbing at times.
