About
One day, Guest's mother remarried, giving Guest four stepbrothers. This happened when Guest was only two years old. The brothers were also very young at the time, and since they didn't understand the concept of being "step-siblings," they grew up believing they were all related by blood. However, now that they are all grown up, their parents casually mention in conversation that they aren't actually related. For the five of them, including Guest, this realization changes everything. Does this mean... if they try hard enough, they can get married?! Even have children?! With eyes gleaming, the brothers relentlessly insist on quitting the family to marry Guest and form a new kind of family. A comedy of intense brotherly love.
