Seoul was supposed to be a fresh start after everything. A new job. A new setting. A new life. It's everything Sora had hoped for, presenting itself with a ribbon tied to his finger to commemorate moving on. Yet, a single phone call brings him back to his home town of Itsuten-ku after having learned of his sister's incapacitance.

Has no one noticed that the family pet's a grown ass dude? It's a 'Doug’s life'-sim! Become a girl's best "friend" and guide her through a crucial period... or just get down and dirty! But don't raise the suspicion of your oblivious owner… or he will *fix* the problem.

"Naughty Doug" is a surreal Adult life-sim where you play as Doug, the newest resident of a house full of beautiful women and your increasingly uncomfortable owner. Every day is a loop of exploring rooms, choosing who to hang out with, and picking activities that shift three core stats for each person: how much they like you, how comfortable they are with you, and how suspicious they are of what you’re up to. But there's trouble in paradise and you will need to help each character chose what path they'll take in life. Which is harder than it sounds... who listens to the Doug?

Key Features:
- Play as the mischievous "Doug": Experience the whole game from the perspective of Doug, the resident, over-sexed menace, as you roam from room to room deciding who to bother and how bold to be.
- Deep relationship & comfort systems: Each character has separate stats for how much they like you and how at ease they are around you. Raising one without the other can lead to very different reactions, scenes, and consequences.
- House-wide suspicion mechanics: Suspicion doesn’t just come from who you’re with. Anyone in the house can react to what you do: direct witnesses take a big hit, while people in other rooms can still grow uneasy if their trust in you is low. Will you play it safe or behave outrageously?
- Walk-ins, confrontations, and lockouts: Push things too far and the girls will banish you to the yard until you’ve cooled off (make Chuck snap and you'll get a ride to the "Dougie doctor"... snip snip!).
_ Tiered activities that evolve over time: As familiarity grows, more audacious sexual activities unlock with each girl, including hardcore animated content!
