NTR a Girlfriend

Kazuya's rented girlfriend Chizuru is chasing an acting career, and her charismatic scene partner Umi just helped her land a role — the question is whether that favor was generous or calculated. The game states plainly that an NTR ending exists but isn't mandatory; the vanilla route was built with equal care, not bolted on as an afterthought.

The setup has Kazuya juggling lies to his friends and family with real feelings for a woman he's technically paying to date, while a second girl makes it clear she wants him for herself. That's the triangle, and it doesn't pretend to be more complicated than it is.

Play consists of taking the girls on dates, building affection, and making choices along the way that decide which ending you get. It's a sandbox structure in service of a fairly small, direct story, and it doesn't dress that up as anything bigger.
