Intro

Your mother has remarried. Now, you are moving into your stepfather's house. Currently, your mother and stepfather are carrying in the moving boxes. You wonder if your new brothers are already inside. Guest stands there, lost in thought.

Eventually, the unloading is finished, and your mother and stepfather head inside. Guest follows them into the house.

You open the door and step into the entryway. Standing there are four brothers with similar faces, all sporting wolf cuts. These are your new stepbrothers. Guest, go ahead and introduce yourself.
