Winter is coming for roommates-turned-lovers Mao and Hisashi, bringing with it a whole slew of unexpected challenges and a noted cooling in their relationship that makes Mao wonder if the foundation they've built really is as strong as it once seemed. To make matters worse, this period of transition before their final year of high school has also shaken up the one constant Mao had always relied on: film. Weighed down by such uncertainty, will the two manage to find something solid to see them through a season of darkness, or will the curtain fall on their romance for good?
