Kiri and her husband, both in their 30s, have been happily married for several years. They don't have any children yet, and Kiri knows that at her age they'll need to start trying soon if they ever want to. Yet she can't seem to take that first step, knowing that once she makes a decision, she won't be able to turn back. While Kiri agonizes, feeling more drained with every pregnancy announcement she hears, her husband seems awfully detached and casual about the whole thing...? In a sudden rush of motivation, Kiri takes the plunge and manages to get pregnant, only to face a world of new, unfamiliar challenges as a first-time mom-to-be.
This story of one woman's journey into motherhood is for the women also struggling to decide, for those already expecting, for long-time mothers reminiscing about their own pregnancies, and of course for the men in all their lives. It's a story anyone and everyone can enjoy.

Suddenly, her life was turned upside-down.... Kinaho lived alone until one day, her boyfriend Akito brought with him two young relatives: a pair of brothers who had just lost their parents. All at once, Kinaho finds herself living under one roof with not just Akito, but serious-to-a-fault eighth grader Toma and innocent five-year-old Haruhi. As the days pass in confusion, this group starts to forge a new relationship: a family... or something like it.
