Snape might face the challenge of his own biases. He has had a long - standing dislike for Harry's father, and this could initially cloud his ability to help Harry. Also, the wizarding community may not fully understand autism, so Snape could face resistance or lack of support when trying to implement special accommodations for Harry.
One major challenge for Snape would be dealing with the other teachers and students. Some teachers may not agree with his methods of helping Harry, thinking it gives Harry an unfair advantage. The students, especially those who are not fond of Harry, might bully him even more for being 'different' and getting special attention from Snape. Moreover, Snape himself has to overcome his own gruff and often unapproachable nature to be able to truly connect with Harry on an emotional level and understand his needs as an autistic person.
One way this could develop is that Snape, initially reluctant, gradually realizes Harry's unique needs due to his autism. He might start by being less harsh in his criticism during potions class. For example, instead of scolding Harry for his mistakes, he begins to patiently guide him. This newfound understanding could lead to a bond between them, and Snape could use his vast knowledge of magic to help Harry find ways to control his magical abilities better in relation to his autism, like developing a spell or potion to ease his sensory overload during chaotic magical situations.
One challenge could be Harry's distrust. Harry has had a long - standing enmity with Snape, so he might be reluctant to accept Snape's help. Another is the complex nature of Harry's problems. Harry has faced so many traumas and has a big destiny to fulfill. Snape might find it difficult to address all these issues without overstepping boundaries or causing more harm.
One challenge would be dealing with Snape's harsh criticism. Snape is not known for being gentle with his words, and Harry would have to learn to take it constructively. Another challenge could be the secrecy involved. Snape has a lot of secrets, and Harry would need to respect that while also trying to figure out what Snape is really thinking. Also, other students might be jealous or suspicious of Harry's new relationship with Snape, which could create some social problems for Harry at Hogwarts.
One big challenge could be Snape's natural inclination towards the Dark Arts. Harry would have to constantly keep an eye on Snape and try to steer him away from that path. Also, Snape's personality is often prickly and guarded. Harry would need to break through those barriers to really connect with him. Another challenge might be the expectations of the wizarding community. People might not understand why Harry is raising Snape and could be suspicious or judgmental.
One major challenge would be the public perception. Snape has a rather dark reputation in the wizarding world, and Harry is a hero. People might not understand or accept their relationship, let alone them having a family. Their family could face discrimination or be the subject of rumors.
One challenge could be his own reputation. Snape has a rather dark and brooding image at Hogwarts. So, other students or even some teachers might be suspicious of his motives for being Hermione's guardian. Also, Hermione is very independent - minded, which might clash with Snape's over - protective tendencies at times.
One major challenge is Harry's initial distrust. Harry has known Snape as a mean - spirited teacher, so it's hard for him to accept Snape as a guardian right away. Also, Snape has to protect Harry from the threats of the wizarding world, such as Voldemort's followers. He has to constantly be on guard and anticipate any potential attacks. Another challenge is dealing with Harry's friends. They might be suspicious of Snape too, which could create problems when Snape is trying to keep Harry safe and make decisions for him.
Well, one of the best aspects is seeing the development of their relationship. In the original books, it was mostly tense. But in fanfiction, we can see Snape truly helping Harry, like teaching him advanced magic or giving him insights about his parents. It gives a new perspective on both characters.

One big challenge is their pre - existing relationship. They've had a lot of conflicts in school. Snape has been rather harsh on Harry, so they need to overcome that animosity. Also, Snape has to deal with Harry's trauma from the Dursleys. He needs to help Harry heal and grow in a positive way, which is not easy for someone as emotionally reserved as Snape.
