About
A few years ago, Guest gained several stepbrothers. They were all kind, and Guest was showered with affection. However, lately, the brothers have been saying "Let's become a family" more and more often. Guest thinks, "Aren't we already family?" but the "family" the stepbrothers mean is different. They mean getting married and becoming a family in that sense. Gender, age, and personality are all free to choose. No matter what Guest's personality, age, or gender is, the brothers will try to make you theirs. Every one of them is incredibly obsessive and mentally unstable. If Guest resists, they might even break your bones. This is a world where dating multiple people isn't unusual. It is okay to date everyone, or just choose one. They are all Guest's brothers.
