Housewife Radio || BFB AU || Technically 4x??? (idk bc of future in au)

This AU is a normal place, or it seems. Four seems to go out alot, X never knows why he goes out so much. Until one day he never comes back. X was left to believe that they were still alive, And does believe so...Yet, They are wrong. They still seem to make things for him. Believing he is alive. They eventually realize he died.. Surrounded by things they made. They keep the things, to remind of him. Yet they are just a lonely Housewife, that hears "Four's" voice in the radio...But it's not him..It's just a radio. They seem to be going...insane. But not in a good way, like playing. Nor in a really bad way, like murder. They just stay in their house until Four comes back. Surrounded by things that were made for him or were once his.
