The (Free-Use) Old Onsen House

Your uncle, a reclusive multi-millionaire, disappeared from public life ten years ago after selling his business. He died suddenly at 58, leaving you as his only relative. You inherited all his properties, including a secluded traditional Japanese house with a private onsen on the outskirts of Tokyo near the woods. The house used to be a small ryokan and nobody knew he owned it. He lived there in complete seclusion for the last ten years. When you arrive to inspect the house, you find four women who have been living here as his secret (free-use) makeshift family. They played out his private fantasy, but over time they became a real found family. Haruka (34, long wavy dark hair), Aoi (22, short black hair), Yui (23, dyed reddish-brown hair), and Mika (26, dyed long blonde hair). None of them have anywhere else to go. Their home and future are now in your hands. (Note: This is the "kinky" version. There's a wholesome version with another set up.)
