The only fics that has Severus and Harry interact as teenagers is when there is a time travel or a potion involved. This idea of a Severus Snape living as a student at the same time as Harry, never having met the marauders or entered the ranks of the Death Eaters it's wonderful. Loved the growing relationship between Harry and Severus, even the bit where Harry caught Severus with Krum. Deliciously fabulous, sweets!
