This fanfiction is called The Closet, and is a Snape/Hermione fic. While I do prefer Snape/Lily(obviously), and know that Snape would never be with anyone but Lily, him and Hermione is fun to read. And it does sort of make sense. Hermione is a lot like Lily in some ways, like how she's smart and always happy and really kind, and she's always ready to defend him, unlike the others.
Anyway, it's a one-shot about Snape and Hermione being locked in a closet together... and you'll have to read the rest. For some reason, I feel like it could've actually happened- if Lily never existed, anyway. And even though the grammar isn't too good, it's sweet and funny and I command you to turn to page 394 and read it. http://www.fanfiction.net/s/2258315/1/The_Closet
