My Only Friend

After many of the remaining heroes of the Second Wizarding War are killed, all Hermione and Sirius have is each other. After they grow too close for a teacher and student, Sirius tries to cut ties with Hermione. She isn't about to let him run away, not if he'll still have her. Rated for near dub-con. Disclaimer: I don't own Harry Potter, nor am I making any money from this.
