He soon starts noticing objects have been moved and there are strange noises coming from empty rooms. It becomes clear that he is not living alone. His initial reaction is to ignore the seven and a half annoying residents, then tries everything he can to get rid of them, but to no avail. Over time, their forced cohabitation falls into a pattern of domestic intimacy and Pietro realises that he is no longer lonely. The lessons he learns from his other-worldly friends have made him braver and truly ready for a new life in which he will never be alone again.
