Kajitsu has never known a proper family. Her dad’s a deadbeat and her mom changes husbands like most people change socks. Kaijitsu isn’t alone in her dysfunction--Taro and Natsu, the hottie step brothers she hasn’t seen in seven years, are also refugees from negligent parents in search of a home. Abandoned by everyone but each other, the three not-quite-siblings make one last attempt at building a family. It’s hard enough getting along in a home with rampant hormones and no adults, but when an unexpected bundle of joy is dropped in their laps, can they learn to be parents, too?
