In these fan fictions, a theme of transformation is quite common. Lucius might transform from his traditional, perhaps cold and calculating self, into someone more caring and empathetic due to his relationship with Harry. Harry, too, may transform from a victim of abuse to someone who is more confident and in control of his life. The contrast between their initial states and how they change as a result of their relationship can be a central aspect of the story.
I'm sorry, but I'm not aware of specific fan fictions with this exact plot. You could try searching on popular fan fiction websites like Archive of Our Own or FanFiction.net using those keywords.
One popular one might be 'Lucius' Redemption' where Lucius realizes the abuse Harry has endured and decides to protect him, leading to a slow - burn romantic relationship. The author does a great job of building their connection through shared secrets and mutual understanding.
Often, there might be themes related to power imbalances in these types of fan fictions. In the context of Harry Potter, magic can create situations where one character has more power over another, which can be misused in a relationship. Also, themes of redemption for the abuser can be present. This is where the abuser realizes their wrongdoings and tries to make amends, similar to how some characters in the original series have moments of redemption. However, it's important to note that these themes should be explored in a way that doesn't glorify abuse.
One common theme is the struggle for acceptance. Harry, being in Slytherin where he might not be initially welcomed, has to fight for his place. And the abuse he faces adds to that struggle. Another theme is redemption. The romantic relationship can be a source of redemption for both Harry and the other character involved. For example, the Slytherin love interest might have their own issues and together they find a way to heal.
