Reincarnated As An Extra So I Cucked The Hero

You get reincarnated into an adult novel, but not as the hero. You're just background filler, and you'd like to keep it that way. No interest in the main plot, no interest in saving anyone; the only agenda is staying invisible while sampling everything the setting has to offer.

That means carving out a living instead of chasing destiny. Early on you can pick up work at the merchant or the inn, grinding through a few days of labor for a proper title, or you can gamble on getting drunk instead and hope one of the random events triggers. It's a small, rough loop right now, more toy than system, but it's the thing standing between you and whatever the hero is off doing.

The cast leans on monster girls, milfs, and a protagonist who isn't locked into one gender presentation, with the usual side dishes of cheating, exhibitionism, and voyeurism baked into the world rather than bolted on. It's early, it's a little janky, and it knows exactly what it's for.
