In an unspecified town in Japan two high school students, Kazuo and Haruka, end up living together under the same roof, one out of desperation and one out of unforeseen empathy and desire for something new. As things develop it turns out that the circumstances the two of them will live by are far from simple. The knowledge of them living beside each other must be kept secret from a certain girl in their class that also is Harukas best friend. Keeping such a secret turns out to be harder than it seemed and there will be no short of troubles coming their way during their time together, especially when feelings start to bloom.
