It's possible that his wife is a former Death Eater who has changed her ways. She and Snape could have a past together in the dark circles but then decided to break free. They support each other in their new lives away from the dark arts and build a relationship based on redemption and love.
She might be an original character created specifically for the fanfiction. This character could be a witch from a far - off land with unique magical powers. She comes to Hogwarts on some sort of exchange program and meets Snape. Their relationship starts off as a friendship that gradually blossoms into love.
Luna Lovegood could be an interesting choice. Her unique and somewhat eccentric personality could complement Snape's brooding nature. She might see through his tough exterior and find the good in him, and their relationship could be based on mutual understanding of the 'outsider' status they both have in different ways.
A possible character could be a fellow Hogwarts teacher. Maybe a new potions teacher who shares Snape's passion for the subject. They could start off as rivals in the classroom but gradually fall in love as they discover their shared interests and values.
Hinata could be a likely candidate in such a fanfiction. Since she is Naruto's real - life wife in the original series. Writers might twist their relationship in fanfiction and create a scenario where she betrays him. Maybe due to some family pressure or a misunderstanding that gets out of hand.
One possible plot could be that they are in a forced marriage. Maybe as part of some dark deal between Voldemort and Dumbledore's side. And they have to learn to live with each other, gradually finding unexpected common ground.

Harry could have a complex relationship with Snape's wife. On one hand, she would be his caregiver, but on the other, there might be some initial tension due to her being associated with Snape. However, over time, she could break through to Harry and they could develop a bond based on mutual respect. She might introduce Harry to a different side of magic, like the more gentle and healing aspects, which would strengthen their relationship.
One possible plot could be that Snape's wife is a powerful witch from a different wizarding family. She might be someone who understands Snape's complex nature and helps him deal with his past traumas. For example, she could be a healer who uses her magic to soothe Snape's troubled mind. They might have met during Snape's time at Hogwarts, perhaps she was a visiting student from another school and they formed a connection that grew over time.
It could be a completely original character created by the fanfiction writer. This gives the writer a lot of creative freedom to design a character that can have a unique relationship with Snape.
Another possibility is that it's a werewolf - human hybrid. This unique being would have the loyalty and protectiveness of a werewolf and the compassion of a human. In the Twilight universe, such a character could be an interesting choice for 'the perfect wife' as she would bring a whole new set of dynamics to the story.
Perhaps an old enemy from Naruto's past that was thought to be defeated has resurfaced. This enemy might have targeted Naruto's wife as a way to get revenge on Naruto for their previous defeats. They could be using her as a bait to lure Naruto into a trap.
