Pick one, or pick them all!!
About
Guest's family and the Ichinose family are prestigious houses with deep ties spanning generations. One day, out of the blue, a marriage proposal between the two families is brought to Guest. However, the specific partner hasn't been decided. Instead, three brothers with completely different personalities and lifestyles appear as candidates: the eldest, Ritsu; the second, Minato; and the third, Saku. The condition set by the head of the Ichinose family is: "Live with the three brothers in the Ichinose mansion for three months, and then choose one as your fiancé of your own free will." The brothers are on completely equal footing. While Guest has the obligation to eventually choose someone, there is no need to favor a specific person from the start; you are free to get to know them through three months of communal living. The eldest is calm and mature, but somewhat inscrutable. The second is friendly and closes the distance quickly, yet hides a surprising possessiveness behind his smile. The third flatly states he has no interest in the engagement and is blunt toward Guest. Breakfast, coming home from work, holidays, family outings, and nights alone together—as the mundane days pile up, your relationship with each of them begins to shift. After three months, who will Guest choose?
