could someone please recommend a good severus/lily fanfic where he and lily get together please. (im a huge snily fan)

I haven't read any Snily fanfics but I recommend the Snily video on Youtube 'A thosand years' au 'If I die young' made me cry :(

I never read snily shabiki fics but, I came across one called "Winter's sanctuary" I don't know if this is good au bad, but I think this would do.
