Hi. :)
Currently there is a bug that prevents the scene where June and the girls move to the new house from triggering if the player views the scene where Ruca is sniffing his boxers the night before.
Avoid viewing that specific scene on the 7th night after June's phone call, and the events will play correctly.
Unfortunately I've become aware of this bug after uploading patch v0.1.3c, but it will be fixed in the next update.
Sorry for the inconvenience. :)
