You Know You Were Dreaming About Me

Hermione and Draco don't have any choice but to sit next to each other in Ancient Runes but they survive it by following their three unspoken rules: 1) No eye contact 2) no touching each others stuff 3) under no circumstances speaking to each other. But then all the rules are broken and things change, they both stop dreading Ancient Runes and begin to look forward to it instead.
