Synopsis
Adapted from the erotic visual novel developed by Candy Soft. The Hanabishi and Hidaka families live right next door to one another, and their fathers are such close friends that both households function like a single extended family. Kouki, the Hidaka family's only son, was especially doted on by the four Hanabishi sisters, who raised him as if he were their own little brother. Then one day, the parents of both families decided to embark on a long-term business trip overseas together. Kantaro Hanabishi's only hesitation was leaving his four daughters behind in Japan. "Don't worry about a thing. I'll take care of them, you can count on me!" With those casual words from Kouki, both sets of parents happily set off on their journey. "Now that's what I wanted to hear! How dependable!" Before leaving, the parents had already arranged for one of the four sisters to be betrothed to Kouki. The matter was supposed to be discussed further after his graduation, but this turn of events provided the perfect opportunity to speed things up. And so, Kouki will spend the entire summer vacation living under one roof with all four Hanabishi sisters. Yurina, the eldest: Competent at her job, but at home she lounges around and works Kouki to the bone. Momone, the second daughter: Completely smitten with Kouki and spoils him endlessly. Saori, the third daughter: Handles all the housework and, though she acts like a maid, prefers staying inside to going out. Anzu, the youngest: Has no qualms about treating Kouki as her personal plaything. Each sister has her own agenda and will stop at nothing—even luring him into intimate situations—to get closer to making the Kouki they love their husband. If Kouki ever has to choose a bride, who will it be? The lively summer with the quartet of sisters is just beginning.
