Film enthusiast Mao Tsuchiya and his lone wolf roommate Hisashi Otomo make three promises: ① That Mao will never tell anyone that Hisashi is gay and has a boyfriend, ② That Hisashi will never approach Mao “in that way,” and ③ That they’ll respect each other’s “private time.”The second-years’ ground rules should ensure a peaceful life together in their dorm, but reality is never as simple as it seems in the movies, and some things are not so easily promised…
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 it 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?
