[An attic? This guy... doesn't have parents? Maybe something bad happened to him? Yu pushes the thought away so he can answer the questions.]

You won't have to live in an attic here. [He smiles.] There are communal buildings and eventually, if you don't like living with a lot of people at once, you can move out.

As for the border, hm. [Yu looks thoughtful,] Some might be looking for a thrill. Others like to investigate. But the basic reason is expanding the quarantine and keeping people living here safe.
