The Dark Lord's Childhood Friend Wants to Be Top of the Class Too

Reincarnated into the Harry Potter universe after dying from overwork, I wake up as an orphan in Wool's Orphanage—right next door to Tom Riddle himself. According to every fanfic trope, I'm supposed to be his childhood sweetheart, his 'white moonlight' destined to save him from darkness. There's just one problem: this future Dark Lord I've fallen for speaks Parseltongue, and I'm starting to realize that changing fate might require more than love—it might require outworking a genius. Welcome to my magical academic survival story.
