The Guardian Spirit behind HP SSOC

After Snape died, he appeared next to the little girl Li Mo, and he couldn't leave, so he just took care of the little girl as his daughter.But when the little girl grew into a little girl, he found that her thinking became more and more strange. Why did she say she liked Professor Snape?This kind of aesthetics is really... well, he admitted, he also... likes her very much.I want to give the professor a life where he can let go of the pressure of the wizarding world. I hope he doesn't need to protect Harry with his life, and he doesn't need to bear the crime of killing Lily and Dumbledore. I hope he can have a good relationship.
