Yes, it is planned and outlined in my roadmap post on patreon (public post). Thank you for playing! :D
Had some ideas. Could make it when the debt goes over 5k that the old man starts to pimp her out to recoup his losses. Like setting up a gloryhole at the bathroom or inviting friends over to the bathhouse. Even have the player pay to get access to her in the bathroom "not knowing its her." Also if you do get her plenty of money to avoid the evil route theres not much access to sex for the mc. Yet theres tons for the old man.
