One way it could start is at Hogwarts. Snape's daughter, perhaps named something like Lyra, could be sorted into Slytherin like Draco. Draco, being the prideful Slytherin, might initially be dismissive of her, but as he sees her inherit her father's intelligence and skill in potions, he becomes intrigued. Their love story could begin with a shared love for academic excellence in the dark arts and potions.
One major obstacle would be Snape himself. As her father, he might be very protective and not trust Draco easily. Snape has seen Draco's family's loyalty to the Dark Lord in the past, and he would be worried about his daughter getting involved with someone from that background.
Dumbledore could be an important character too. He might be aware of Snape's daughter's existence and see the potential in her relationship with Draco. He could be the one guiding them, or at least observing from afar, making sure their relationship doesn't cause any major disruptions in the wizarding world.
One possibility could be that Snape's secret daughter, let's call her Lily (for the sake of this story), has been hidden away all her life. Draco, being from a prominent pure - blood family, initially has doubts about her. But as they interact more, he realizes she has a kind heart and a sharp mind, much like her father. They might end up forming an unlikely friendship, which then develops into something more as they face the challenges of the wizarding world together, such as dealing with the remnants of Voldemort's followers.
A potential plot could be that Draco is tasked with finding Snape's secret daughter for some unknown reason. When he does, he's surprised by her resemblance to Snape in terms of her intelligence and determination. They begin to work together to solve a mystery related to Snape's past, which gradually builds a bond between them.
Well, it could be about the daughter of Snape secretly having feelings for Draco Malfoy. Maybe she's been in the shadows all this time, and when she meets Draco, there's an instant attraction. Their relationship might develop against the backdrop of the wizarding world's politics and power struggles.
Definitely. Some fanfictions depict Snape as secretly mentoring Draco. He might share some of his own wisdom or skills with Draco that he wouldn't share with other students. This could be because he understands the pressure Draco is under from his family. Also, in certain fanfic scenarios, Snape is shown to be there for Draco when Draco has personal problems or is being bullied by other students.
Well, Snape's care can make Draco more confident. Knowing he has someone like Snape looking out for him gives him a sense of security. This can lead to Draco being less arrogant and more self - aware. He might start to question some of the pure - blood supremacist ideas he was raised with, as Snape's care could show him that there are more important things than just blood status.
Snape could also punish Draco by deducting house points. Since Draco is in Slytherin, losing house points is a big blow to his pride and to the whole Slytherin house. This would make Draco the target of his housemates' ire, adding to the punishment's severity.
In some fanfictions, Snape as Draco's godfather can be portrayed as a very protective figure. He might use his influence in Hogwarts to shield Draco from various troubles. For example, he could ensure Draco gets preferential treatment in Potions class or intervenes when Draco gets into minor scrapes with other students. Snape's complex personality adds an interesting layer to this relationship. His loyalty to the Dark Lord on one hand and his newfound role as a godfather on the other create a great internal conflict for his character in these stories.
