Yea, that's what I'm saying. He had the choice to do whatever he likes with the game he created. Didn't he say he particularly liked the shipping of Lychoris and that spoiled kid, and the heroine with the male lead? And he really seemed to like the idea of a yandere when Lychoris brought it up.

He writes his favorites down in his notepad, it's not a big surprise that he chose his own personal favorites to include in the game since he can't add all thousands of them. Maybe yandere is his fetish for all we know. The characters, particularly the love interests, might not really be yanderes here...there was just that one in a million chance that they'd turn out to be that he chose to include in the game.

that guy picked the worse case scenarios and twisted it to and added his own spin. Because she did teach him about the concept of Yandere. He may have made fictional timelines based on the real.

It was just a theory. She just guessed that that was the reason for there being an otome game about this world in her previous world. Even still, it is one of the best explanations I've ever seen in those reincarnated in otome game stories. Plus, it gets rid of the thought that this is a world inside a game and makes you look at it as an actual other world on which a video game was based on. Also, best thing is that it basically says the characters are not really all yanderes...its just a select few of the millions of possibilities that guy saw and liked.
