In one, a 'goddess' create otome game then transport people who clear it to that world and watch them recreate the scenarios.
The main character is a demon who's made a 'contract' with one of the villainess in the story, and is in this world to fulfill it...and completely crush anyone who try to touch her ojou-sama.
The 'protagonist' in that one are basically a bunch of people who cleared the game and thus feel as long as they can trigger the 'event' everything will go well....
(It was some kind of otome MMO game where players can interfere with each other and the winners are the ones who manage to get a good ending in their time)
In another, a girl died and was given a chance to reincarnate in a world that her favorite VRMMO is based on.
Instead she somehow reincarnate as a villainess in an otome game that set in a suspiciously similar world (turns out they're the same world)
And so, she must now try to survive as a character who has so many death flags hanging in her life that it's a mystery how'd she survive so long.
In this one, the game's real heroine is....a psychopathic level of egomaniac moneygrubbing miser, whose thoughts are always about herself and thus is totally oblivious to how others feel.
She'd charge 'friendship fee', try to sell fake charms, befriend the capture targets to try and use their high status to open her own store, etc.
