I wonder what other stuff the dev will include in this release. By manager, that's Millina reappearing in the story (and if she's not careful in the story, her daughter might have a new sibling) And that mansion is about to become rather cramped, if the protagonist continues to go along with his "go forth and multiply" campaign (and there are still some ladies who have yet to become mothers in the story).
