I disagree. Like the other person said. She never finished the game. She died every single time before the coming of age event. Eclis never became a yandere (wasn't twisted)in the game both in Yvonne playthrough while in og Penelope playthrough she couldn't have known.
Imagine getting isekaid in idk Code realize or Tokimeki girl side games. There are no yandere in this game (some say Saint Germain is a yandere. They're delusional. The guy kidnapped Cardia/mc because he was ordered not because he loved her). If you get isekaid in this very fluff, optimistic, raindow colored games you wouldn't expect the character to be twisted. Same way if you get isekai in an otome you haven't like Tengoku struggle (a new otoge coming this year), you have no clue how the characters will be.
I don't think initially in the game if you play as Yvonne (the super easy route) that there were many bad ends at all? It seemed that she was loved through and through by all the male leads too.
Yes I'd agree with the survival instinct really killing away all rational thought about game mechanics lol. Now it ain't as simple as 100% = clear
No. I don't remember where in the novel, but no. Penelope's playthrough was an expensive and money grabbing DLC. It shows once in the webtoon too. If Penelope dies in a bad end she has to PAY real money to restart. The Penelope's story is hard because 1) too many unreasonable bad ends 2) the Penelope micro transaction of og Penelope's playthrough discourage people to play it ergo there ARE no guide online = Reason why Siyeon (sorry if wrote wrong) keeps failing and never went past the coming of age event. He can assume the dlc was added later recently.
As angsty and harrowing as all these new developments are, I do think it's kind of funny/ironic that Penelope didn't forsee this possibility with Eclis before now. Like, the whole reason any of this is happening is because girl got herself trapped in an otome game. Bad ends with an obsessed yandere are a pretty common feature in otome games. Penelope's gotta get good.
In all seriousness, I understand why someone realistically would forget about game mechanics when they're constantly afraid for their life, but still. Kinda funny that all this drama is still par for the course in a dating sim.
